摘要
通过对装配式剪力墙破坏特征的分析,提出方便分析计算的等效斜撑模型。基于FEMA356中提出的斜撑宽度计算公式,利用OpenSees分析平台建立原始参照模型和等效斜撑模型对计算公式进行改进,提出了更为准确的斜撑宽度计算公式。对不同跨高比、不同墙厚和不同轴压比情况下公式的适用性进行了分析,验证了斜撑宽度计算公式良好的适用性。可以利用此公式求解等效斜撑模型宽度,从而简化装配式剪力墙计算分析。
Based on the analysis of the failure characteristics of the prefabricated shear wall,an equivalent diagonal bracing model was proposed to facilitate the analysis and calculation.Based on the calculation formula for diagonal brace width proposed in FEMA356,an original reference model and an equivalent diagonal brace model were established by using OPENSEES analysis platform to improve the calculation formula,and a more accurate calculation formula for diagonal brace width was proposed.The applicability of the formula under different span height ratio,different wall thickness and different axial compression ratio was analyzed,and the good applicability of the formula for calculating the width of diagonal bracing was verified.This formula can be used to calculate the width of the equivalent diagonal brace model,so as to simplify the calculation and analysis of the prefabricated shear wall.
