Embodiment Construction

[0040] The invention will be further described below in conjunction with specific embodiments:

[0041] This embodiment provides a frame structure building anti-seismic reinforcement method based on the concepts of controlled sway structure system, damage control, and replacement. This method can be used for both existing frame structure buildings and new frame structures. In the building, the number of floors of the frame structure building can be determined according to actual needs. In this embodiment, a four-story frame structure building is used as an example for illustration. It is the same as a conventional frame structure building. The bottom of the four-story frame structure building Set with foundations.

[0042] Such as Figure 1-Figure 5 As shown, the frame structure building seismic reinforcement method provided in this embodiment includes the following steps:

[0043] S1, evaluate the uneven coefficient of floor lateral displacement and structural performance o...

Abstract

The invention provides an anti-seismic reinforcing method for a frame structure building. The anti-seismic reinforcing method comprises the steps that the floor lateral displacement unevenness coefficient and the structural performance of the frame structure building are evaluated to obtain an evaluation result; according to the evaluation result, the setting positions and the setting number of ridge strengthening units on the frame structure building are determined, and a construction drawing is drawn; and the ridge strengthening units are arranged on the frame structure building according tothe construction drawing to complete the steps of seismic strengthening and the like of the frame structure building. Lateral deformation of the frame structure building can be effectively controlledby arranging the ridge strengthening units, weak layers of the structure are effectively avoided, an expected damage mechanism can be achieved, and meanwhile the ridge strengthening units are flexible in plane layout, convenient and fast to construct and easy to apply and popularize.

Description

technical field [0001] The invention relates to a building strengthening method, in particular to a frame structure building anti-seismic strengthening method. Background technique [0002] Among all kinds of concrete buildings, the frame structure is one of the most used structural forms at present. The existing earthquake damage shows that the structural damage of the frame structure buildings is often concentrated due to the uneven lateral deformation of the floors, forming a weak floor. Under such circumstances, the residual deformation of the structure is too large, which exceeds the maintenance value, and even the structure collapses, and the expected structural failure mechanism is difficult to realize. [0003] In view of the above problems, some domestic and foreign scholars have proposed to use swing wall technology to control the lateral deformation of frame structure buildings, avoid the concentration of floor damage caused by the uncertainty of earthquake input ...
