Embodiment Construction

[0030] In order to clearly illustrate the solutions of the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the application or uses of the present disclosure.

[0031] It should be understood that some basic technical concepts involved in the present invention, such as elastic model, static analysis, seismic response spectrum analysis, etc., are known per se, so this article focuses on the design method of the atrium through-story frame column involved in the present invention principles and applications.

[0032] see Figure 1 to Figure 3 In this embodiment, the design method of the atrium penetrating frame column based on the equivalent stiffness includes the following steps:

[0033] S101. Establish the elastic model of the frame structure without openings in the floor slab, that is, the first model...

Abstract

The invention provides an atrium cross-floor frame column design method based on rigidity equivalence. The method includes respectively establishing a floor slab non-holing model (a first model) and afloor slab holing model (a second model), and carrying out the static and seismic response spectrum analysis; based on a first model meeting specification requirements and an elastic analysis resultof the first model, respectively extracting the floor lateral stiffness of the two models, according to the principle that the floor lateral stiffness of the first model is equivalent to the floor lateral stiffness of the second model, amplifying the earthquake action of a cross-floor frame column (namely a frame column within a floor holing range) in the second model, and carrying out component reinforcement design to achieve the effect that the earthquake resistance indexes of the first model and the second model are similar. According to the method, aiming at the problem that earthquake shearing force distributed to the cross-floor frame column is small due to the fact that a large hole is formed in a floor slab, the amplification coefficient based on floor lateral stiffness equivalenceis provided, the anti-seismic contribution of the cross-floor frame column is improved, the anti-seismic performance of the whole structure is improved, and reference is provided for similar engineering projects.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to a design method for an atrium through-story frame column based on equivalent stiffness. Background technique [0002] For a large number of public buildings such as commercial buildings, medical buildings, and offices, due to the requirements of building facades and floor plan layouts, floor-penetrating frame columns caused by large holes in the floor slabs have generally appeared in the current structural design. [0003] The mechanical properties of frame structures with story-through frame columns are different from those of conventional frame structures, especially in the redistribution of internal forces after the structure enters plasticity. However, the current relevant codes and standards do not specify the strength of story-through frames. Design method of column structure. The frame structure with story-piercing frame columns has different deformation capabilities...
