简试

介绍了有限元分析的理论基础，用ANSYS软件对四边简支板试件进行了实体建模，比较了三维实体模型和平面模型特点，并指出了采用平面模型进行建模的合理性；

Base on the basic theory of finite-element analysis , hypostatic modeling for four-side simple supporting plank was upbuilt with ANSYS software . Three-dimensions hypostatic model and plane model were present by simulating the strain distribution of four-side simple supporting plank with damage using finite-element analysis software .

这是简第一次试着绣花。

This is Jane 's first attempt at embroidery .

完成的主要工作和取得的成果包括：1.设计了以栓钉抗剪连接程度为主要参数的11根正向和反向加载简支组合梁试件，以及3根两跨连续组合梁试件。

The main works and results are as follows : 1.11 simple supported specimens under positive or negative bending moment and 3 continuous members were designed taking the degree of shear connection as main factor .

针对这些问题，本文主要包括以下内容：1、本文通过5根正向和反向加载简支组合梁试件的实验研究，得出了各试件的破坏过程及裂缝分布图。

To solve these problems , this paper includes the following content : 1 . In this paper , 5 positive and nagative loading of simply supported composite beam specimen were researched and reached the failure process and crack distribution .
