load stage
Examples
- Through comparing and analyzing of bearing capacity , development of crack and strain of reinforced , the results show that the load - deflection plots f or specimens from the finite element analysis agree well with the experimental data , and choosing the rightful stress - strain relationship , utilizing ansys program , the test process can be well simulated . at the same time , making used of the program , the traditional shear wall is analyzed . it shows that comparing with the traditional shear wall , the hollow shear wall ' s cracking load drop 16 % , yield load and failure load drop 13 % , stiffness drop 13 % ~ 22 %
其次在试验的基础上，将试验手段、有限元数值模拟方法和理论分析结合起来，利用有限元程序ansys对其中的两片墙板进行非线性有限元分析，并对前后的承载性能，裂缝发展、钢筋应变进行了比较和分析，结果表明有限元节点模型分析的荷载-位移曲线和试验测得数据符合良好，选用合理的材料本构模型，利用ansys可以较好的模拟试验过程；同时利用有限元模型对比分析了普通剪力墙和空心剪力墙，空心剪力墙与普通剪力墙对比，其开裂荷载下降16 ，屈服荷载、极限荷载下降13 ，刚度下降13 22 ，开裂至屈服、屈服至极限荷载阶段的刚度衰减规律与普通剪力墙基本一致，空心剪力墙的后期刚度比较稳定。 - The friction coefficient , critical vertical loads and critical frictional resistance strength have been worked out by means of the pullout tests under the different vertical loads , analysis of frictional characteristics between soil and material and analysis of the different work mechanism between direct shear test and pullout tests . the creep characteristic parameters of some typical reinforcement materials have been obtained by the creep tests under the loads for a long time and the rheological analysis
对几种典型筋材在不同法向荷载下进行了拉拔试验，并进行了筋材与土介质的界面摩擦特性分析，直剪试验与拉拔试验不同机理分析，找出了影响摩擦特性试验结果的主要因素；得出了筋材在工作荷载阶段的摩擦系数、临界法向中南大学博士学位论文荷载和临界摩阻强度。
