多层建筑框架结构光弹性应力分析

Photoelasticity Stress Analysis of MultiLayered Building Frame Structure

对多层建筑框架结构在风载下的应力分布进行光弹性分析，通过模型梁和柱的等差线，测出其反弯点位置及剪力值，算出梁和柱端部弯矩值．同时，对该结构进行了有限元计算，并将光弹性分析、有限元计算和Ｄ值法的结果进行了比较．

The stress distribution of a multilayered building frame structure under windloads is analysed with the photoelasticity.Its location of inversed bending point and shear forces are determined by means of the isochromates of the beams and columns in a model.The bending moment in the end of the beams and columns is calculated.The finite element analysis of the structure is also carried out.Finally,the results of the photoelasticity experiment,the finite element analysis and the Dvalue method are compared with each other.
