在ETH Zurich完成了6个钢筋混凝土墙准静力循环试验,并对试验结果进行分析。这些大比例尺的试验对不同竖向钢筋配筋率和欧洲中部不同延性钢筋的钢筋混凝土墙的变形性能进行研究。试验单位提供的整体和局部性能的试验数据都可联机使用,以供研究单位参考。试验结果显示:配筋率、翼缘和腹板的延性对于钢筋混凝土墙的性能至关重要。通过比较从试验中获得的基础曲率与截面分析得到的曲率,建议在塑性铰分析中区分应变极限与极限状态,在钢筋混凝土结构墙的评估和基础性能设计中采用应变极限。
Six quasi-static cyclic tests of reinforced concrete walls were completed at ETH Zurich and the test results were analyzed. These large-scale tests studied the deformation behavior of reinforced concrete walls with different vertical reinforcement ratios and different ductile rebar in central Europe. The experimental unit provides the overall and local performance test data can be used online for reference by the research unit. The test results show that the reinforcement ratio, the ductility of the flange and the web are crucial to the performance of the RC wall. By comparing the base curvature obtained from the test with the curvature obtained from the cross-section analysis, it is advisable to distinguish the strain limit and the limit state in plastic hinge analysis and to apply the strain limit in the evaluation and basic performance design of reinforced concrete wall.
