Problems solved by technology

The vertical stiffness of the inclined column is smaller than that of the ordinary straight column. Under the action of vertical load, the vertical displacement difference between the inclined column and the straight column on the same floor affects the stress state of the component, and the difference in the constru

Example Embodiment

[0032] Taking an office building as an example, the method of the present invention realizes the design of a continuously changing direction reinforced concrete column structure system.

[0033] The office building has 8 floors above ground with a total structure height of 36m. The horizontal column network adopts the form of 8.4m horizontal and 7.6~13.2m column spans in the depth direction. The middle two struts are straight columns or shear walls. The outer facade columns are inclined columns. The slope of the inclined columns changes continuously. Inclined outside, 5-8 layers of inclined columns inclined inward, and 1 layer of columns are V-shaped inclined columns. Such as figure 1 , figure 2 As shown, the design method steps are as follows:

[0034] 1) Establish a structural design model and complete the calculation.

[0035] 2) Adjust the model. The lateral rigidity of the inclined column is relatively large, and the horizontal rigidity of the structure where the inclined co...

Abstract

The invention discloses a continuous direction change reinforced concrete column structure system design method. According to the method, structural internal force change caused by different construction schemes is simulated in the structural design process, so that the problem that the systems need to be combined with the construction schemes is solved, and the economic rationality of the structure design and the construction scheme is considered at the same time; vertical deformation displacement indexes are proposed, so that the sections of various components in the systems are reasonable and economic; and by combining the horizontal force and distribution difference of floors, the horizontal force problem is solved by adoption of pre-stressed steel reinforced concrete beams, pre-stressed concrete beams and common steel reinforced concrete beams, and components of the floors are design according to compression-flexure or tension-flexure components according to tension/compression stress values.

Description

technical field [0001] The invention relates to the field of reinforced concrete structures, in particular to a design method for a continuous direction-changing reinforced concrete column structure system. Background technique [0002] With the development of architectural technology, architectural shapes are becoming more and more diverse and complex, and oblique columns are often used partially or in large quantities in buildings. The application of inclined columns makes the mechanical characteristics of the structural system different from that of conventional structures. Slanted columns cause horizontal force on the floor structure, and the continuously changing slope of reinforced concrete slanted columns will cause different magnitudes and distributions of horizontal forces on different floor structures. The vertical stiffness of the inclined column is smaller than that of the ordinary straight column. Under the action of vertical load, the vertical displacement dif...
