Steel plate concrete shear wall column reinforcement design method

Abstract

The invention provides a steel plate concrete shear wall column reinforcement design method which comprises the following steps: firstly, analyzing and calculating an overall structure model to obtaina design internal force, an axial force, a bending moment and a shear force of each wall column; calculating the axial compression ratio of the wall column, and determining the type of an edge component so as to determine the minimum value of the corresponding construction measure requirement; determining the profile steel area Aa configured in the shadow part of the edge component; determining the area Ap of a steel plate configured in the shear wall according to the shear section limit value condition, and determining the type of a calculation formula according to the numerical range of theAp; determining the reinforcement ratio of the vertical distribution bars of the wall column; checking and calculating the bearing capacity of the normal section, obtaining the area As of the longitudinal reinforcing steel bars configured in the shadow part of the edge component by taking the larger value of the bias voltage and bias tension calculation result, and determining the calculation mode according to whether As exceeds the limit or not; calculating the shear capacity of the oblique section to obtain the area Ash of the horizontally distributed steel bars of the shear wall, and determining the calculation mode according to whether the area Ash of the horizontally distributed steel bars of the shear wall exceeds the limit or not.

Description

technical field [0001] The invention belongs to the field of architectural design, and in particular relates to a design method for reinforcement reinforcement of steel plate concrete shear walls. Background technique [0002] Regarding the theoretical research on the design of steel plate shear walls, many scholars have conducted experiments and researches, and formed national codes and regulations. Among them, the more important and commonly used composite structure design code is JGJ138-2016, which includes Chapter 9 Steel Concrete Shear Force Design specifications for walls, including bearing capacity calculation and construction measures, also include design specifications for steel plate concrete shear walls in Chapter 10, also including bearing capacity calculations and construction measures. In the design of steel plate shear wall members, it is necessary to specify the area of ​​vertically distributed steel bars outside the shadow part of edge members, the area of ​...

Problems solved by technology

Therefore, in the section design of steel plate shear wall members, the current relevant codes do not give the design process, and the calculation results may be different if the design process is different

In addition, because the area of ​​the profiled steel of the inner and outer members of the wall is related to the area of ​​the longitudinal reinforcement, and the area of ​​the steel plate is related to the area of ​​the horizontally distributed reinforcement in the wall, and the current relevant codes do not have a design process for the reinforcement, resulting in further inaccurate calculation results
