According to the standard and request of mechanical structures for electronic equipment tests, the finite element model of the electronic equipment cabinet was built by using the software of finite element analysis-ANSYS and simulated the tests of random vibrations by loading and calculating. The 3-D isopleths graph of deformation and stress of the cabinet was obtained. It could confirm the maximum of deformation and stress of the cabinet and probability of occurrence. Through more analysis of the frequency response curve reflected directly and clearly the deformation of the cabinet within the particular seismic frequency.

根据电子设备机械结构随机振动试验的标准和要求，采用有限元分析软件ANSYS建立电子设备机柜结构的有限元模型，通过加载求解对其进行随机振动试验的数值模拟，得到机柜有限元模型的三维变形和应力等值线图，进而确定机柜承受应力和变形的最大值及发生概率；通过对频率响应曲线的进一步分析，可以直观明了地反映出机柜承受一定频率范围地震下的变形情况。

In the static test on Yi'an Bridge in Chongyi,we take a detailed examination and analysis about the flexivity、reinforcement stress、concete stress、steel wires stress of the steel-reinforced concrete、the low prestressing concrete and the full prestressing concrete on the twenty-meter long beam.

在崇义义安桥的静载试验中，对20 米标准跨径的普通钢筋混凝土、低预应力混凝土、全预应力混凝土空心板梁在均布荷载作用下的控制截面的挠度，钢筋、混凝土、钢绞线的应力作了较详细的试验、分析。

This thesis is based on October 8, 2005 7.6-level earthquake reconstruction in the Pakistan disaster areas. Pakistan Earthquake Bureau designed the architectural standard as the background of the China-Pakistan cooperation project, and a sub-project under the standard is discussed in this thesis. Ordinary sintering brick and stone-dust mortar masonry are set as window walls of masonry walls construction, which is also the object in this thesis. Based on the quasi-static experiment, the masonry walls earthquake damage patterns and seismic behavior are studied, underlining Pakistan formulation of the unified national standards for architectural design with basic data.
