箱形截面钢压弯构件受循环弯矩作用的试验研究和理论分析

Experiment and Analysis of the Box-section Members with Compression and Flexure Under Cyclic Bending

本文对不同轴压比和板件宽厚比的15个受常轴力、循环弯矩作用的箱形截面钢压弯构件进行了试验研究，得到了构件的滞回性能特性及主要影响因素。通过与理论分析的比较，验证了理论分析的可靠性和一般性，表明理论分析结果能够应用于工程实际。

The hysteretic behavior and the relative influencing factors of box-section members with compression and flexure under cyclic bending were investigated by a series of tests through 15 specimens. These specimens are divided into three classes in terms of axial compressive ratios 0, 0.4 and 0.6, respectively. The loads are added to the free end of specimens.Then by comparing the test results with those of the analysis, it was verified that the analysis was reasonable and could be used in practical use.
