[0002] During the construction of super high-rise buildings, curtain walls and secondary structures are often interspersed, and settlement post-casting strips are the key to affecting the construction of secondary structures. However, due to the large settlement deformation of super high-rise buildings, it is easy to cause a settlement difference between the podium and the main building. In order to avoid the settlement problem caused by the settlement post-casting strip, the strategy adopted by the existing technology is to wait until the main structure is completed and the settlement is basically stable before pouring the settlement post-casting strip, but this strategy will delay the construction period for a long time and affect the delivery of the overall structure.

[0031] Please also see Figure 1 to Figure 2 A preferred embodiment of the present invention provides a construction decision method for early insertion and closure of post-cast strips of super high-rise building structures, comprising:

[0032] S1, using the standard construction simulation method, conducts a full-process construction simulation analysis of super high-rise buildings to obtain the changing trend of the simulated settlement difference between the podium and the main building.

[0033] This process is super high-rise construction simulation analysis, which can be performed using the structural analysis software MIDAS / GEN, or other software with construction simulation analysis functions. Figure 2 As shown, the main steps of S1 are as follows:

[0034] S11, establish a construction simulation analysis model, apply loads and specify boundary conditions.

[0035] S12, establishing a structure group according to the construction plan, designating the components to be constructed simultaneously as a structure group, and establishing a load group and a boundary group according to the construction step.

[0036] S13, specifies shrinkage creep coefficient and concrete strength development function, and connects to the corresponding components.

[0037] S14, defining construction phase analysis data according to the actual construction plan, the construction phase analysis data including the construction step and the corresponding structure group, load group and boundary group.

[0038] S15, conduct construction simulation analysis and load combination to determine the settlement difference between the building podium and the main building.

[0039] S2, monitor the settlement difference between the podium and the main building, and determine the changing trend of the measured value of the settlement difference between the podium and the main building based on the monitoring data.

[0040] This process is the post-casting belt construction monitoring, and the static level and other devices can be used to monitor the internal and external settlement difference of the post-casting belt of the main building and the podium of the super high-rise building. Monitoring can set one monitoring point, and the data obtained is relatively accurate. If more accurate data is to be obtained, more than two monitoring points can be set. By combining the data of each monitoring point, the actual measured data of the settlement difference will be more accurate. This embodiment uses two monitoring points, and the monitoring results are as follows: Figure 7 , 8 The monitoring results show that as the construction progresses, the difference in settlement between the main building and the podium continues to increase. Since March 1, the growth rate of the difference in settlement between the main building and the podium has significantly accelerated. Figure 7 The maximum settlement difference measured at measuring point 1 is 11.879 mm. Figure 8 The maximum settlement difference measured at the measuring point No. 2 is about 11.239mm. It is also found that between September 19 and September 23, the settlement value of point No. 2 increased, with the maximum increase of 1.030mm.

[0041] S3, using the Pearson correlation coefficient formula, evaluate the changing trend of the simulated settlement difference value between the podium and the main building and the changing trend of the measured settlement difference value, and obtain the correlation coefficient between the changing trend of the simulated settlement difference value between the podium and the main building and the changing trend of the measured settlement difference value.

[0042] This process is the comparison of settlement trends. Combined with the construction simulation analysis data, the settlement deformation trend of the structure is predicted. The calculated settlement deformation of the structure (simulated settlement difference value) is consistent with the measured settlement deformation (actual settlement difference value). The trend is evaluated using the Pearson correlation coefficient.

[0043] The Pearson correlation coefficient, also known as the product-moment correlation coefficient, was first proposed by Karl Pearson. It is mainly used to analyze the linear correlation between time series data and is widely used in signal analysis, fault diagnosis, numerical prediction and other fields. The Pearson correlation coefficient can be represented by P.

[0044] S4, determine the post-cast strip closure construction strategy based on the correlation coefficient.

[0045] Among them, the post-casting belt closure construction strategies include:

[0046] If the correlation coefficient is in the highly correlated section and the residual settlement difference is not greater than the closure construction threshold, all post-casting strips are directly closed, such as Figure 3 shown.

[0047] If the correlation coefficient is in the moderate correlation section and the residual settlement difference is not greater than the closed construction threshold, the horizontal section of the post-casting strip is closed, and the post-casting strips at the four corners are reserved and not closed until the overall construction is completed. Figure 4 shown.

[0048] If the correlation coefficient is in the weak correlation section and the residual settlement difference is not greater than the closed construction threshold, the horizontal section of the post-cast strip is closed, and the post-cast strips at the four corners are not closed. After the overall construction is completed, the horizontal section and the four corners are closed. Figure 5 shown.

[0049] If the correlation coefficient is in the non-correlated section and the remaining settlement difference is not greater than the closed construction threshold, the post-casting strip will be closed after the overall construction is completed and the settlement trend tends to be stable, such as Figure 6 shown.

[0050] The plan shapes of the main building and the podium are both rectangular. The podium is surrounded by the outer circle of the main building. A post-cast joint is set between the main building and the podium. Therefore, the post-cast joint includes four sides and four corners. The four sides are the aforementioned horizontal sections. The horizontal section of the post-cast joint is closed by spanning, which means dividing the horizontal section into several unconnected small sections. Each small section is separated by a certain distance, and each small section is closed first.

[0051] The Pearson correlation coefficient P is a constant between 0 and 1. The closer it is to 1, the higher the correlation between the two quantities, and the closer it is to 0, the lower the correlation between the two quantities. The highly correlated segment (meeting the highly correlated requirement), the moderately correlated segment (meeting the moderately correlated requirement), the weakly correlated segment (meeting the weakly correlated requirement), and the non-correlated segment (meeting the non-correlated requirement) are all pre-set and set according to the empirical values ​​obtained from actual construction. In this embodiment, the highly correlated segment is set to 0.8≤|P|≤1, the moderately correlated segment is set to 0.5≤|P|<0.8, the weakly correlated segment is set to 0.3≤|P|<0.5, and the non-correlated segment is set to 0≤|P|<0.3.

[0052] The closed construction threshold is also an empirical value, which is expressed as a fraction of the span of the post-casting strip, that is, the ratio of the remaining settlement difference to the span of the post-casting strip is within a relatively small range, which can ensure that the post-casting strip will not have cracks and the like. In this embodiment, the closed construction threshold is set to one two thousandth of the span of the post-casting strip, that is, the span of the post-casting strip is L, and the remaining settlement difference does not exceed L / 2000. If the remaining settlement difference does not reach below the closed construction threshold, the closed construction conditions of the post-casting strip are not met, and it is necessary to wait for the main building and the podium to continue to settle until the remaining settlement difference meets the closed construction threshold.

[0053] Before the construction of a super high-rise building, it is necessary to survey the construction site to predict the extent of the settlement of the super high-rise building and monitor the settlement of the super high-rise building in real time during the construction process. This will allow a relatively accurate prediction of the remaining settlement of the main building and the podium during the construction process, and then estimate the remaining settlement difference to determine whether the remaining settlement difference mentioned above reaches the conditions for the post-pouring zone closure construction.

[0054] like Fig. 9 As shown, the embodiment of the present invention also provides a construction decision system for early insertion and closure of post-cast strips of super high-rise building structures, including:

[0055] The simulation module is used to conduct a full-process construction simulation analysis of super-high-rise buildings using standard construction simulation methods to obtain the change trend of the simulated settlement difference between the podium and the main building;

[0056] The monitoring module is used to monitor the settlement difference between the podium and the main building, and determine the change trend of the measured value of the settlement difference between the podium and the main building based on the monitoring data;

[0057] A correlation evaluation module is used to evaluate the change trend of the simulated settlement difference value between the podium and the main building and the change trend of the measured settlement difference value by using the Pearson correlation coefficient formula, and obtain the correlation coefficient of the change trend of the simulated settlement difference value between the podium and the main building and the change trend of the measured settlement difference value;

[0058] The decision module is used to determine the post-casting strip closure construction strategy based on the correlation coefficient.

[0059] Post-cast strip closure construction strategies include:

[0060] If the correlation coefficient is in the highly correlated section and the residual settlement difference is not greater than the closure construction threshold, all post-casting strips are directly closed;

[0061] If the correlation coefficient is in the moderate correlation section and the residual settlement difference is not greater than the closed construction threshold, the horizontal section of the post-casting strip is closed, and the post-casting strips at the four corners are reserved and not closed until the overall construction is completed;

[0062] If the correlation coefficient is in the weak correlation section and the residual settlement difference is not greater than the closed construction threshold, the horizontal section of the post-cast strip is closed, and the post-cast strips at the four corners are not closed. After the overall construction is completed, the horizontal section and the four corners are closed;

[0063] If the correlation coefficient is in the non-correlated section and the remaining settlement difference is not greater than the closed construction threshold, the post-casting strip will be closed after the overall construction is completed and the settlement trend becomes stable.

[0064] Among them, let the correlation coefficient be P, the highly correlated segment is 0.8≤|P|≤1, the moderately correlated segment is 0.5≤|P|<0.8, the weakly correlated segment is 0.3≤|P|<0.5, the uncorrelated segment is 0≤|P|<0.3, and the closed construction threshold is one two thousandth of the span of the post-casting strip.

[0065] Among them, Fig.10 As shown, the analog module includes:

[0066] Modeling unit, used to establish construction simulation analysis model, apply loads and specify boundary conditions;

[0067] The grouping unit is used to establish structure groups according to the construction plan, designate components to be constructed simultaneously as a structure group, and establish load groups and boundary groups according to the construction steps;

[0068] Connection elements, which are used to specify shrinkage creep coefficients and concrete strength development functions and are connected to the corresponding components;

[0069] Definition unit, used to define construction phase analysis data according to the actual construction plan. The construction phase analysis data includes construction step length and corresponding structure group, load group and boundary group;

[0070] The analysis unit is used to conduct construction simulation analysis and load combination to determine the settlement difference between the building's podium and main building.

[0071] Among them, in the monitoring module, the settlement difference between the podium and the main building is monitored, and there are at least two monitoring points.

[0072] The embodiment of the present invention also provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, each process of the above-mentioned super high-rise building structure post-casting strip early insertion and closure construction decision method embodiment can be achieved, and the same technical effect can be achieved. Among them, the computer-readable storage medium is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc.
