Presidential Young Investigator Award - Seismic Analysis andDesign of Unanchored Liquid Storage Tanks

这是1988财政年度发起的总统青年研究者奖。要进行的研究涉及一类一般问题，其中结构的典型振荡周期与非弹性体积应变积累的时间或孔隙压力变化所需的时间相比很小。另外，数值模拟将用于评估新设计的在线伪动力测试方法所得到的分析结果。现有的有限元程序（ABAQUS）将用于模拟交叉支撑构件的局部屈曲现象。这些都是基础研究，将加强对地震工程实践中经常遇到的结构动力学问题的理解。

This is a Presidential Young Investigator Award initiated in FY 88. The research to be carried out deals with a general class of problems in which the typical periods of oscillation of the structure are small compared to the time over which inelastic volumetric strains build up, or the time required for pore pressure changes. Separately numerical simulation will be used to evaluate the analysis results obtained from using newly devised on-line pseudodynamic testing approach. An existing finite element code (ABAQUS) will be used to model local buckling phenomena in cross bracing members. These are fundamental research which would enhance the understanding of structural dynamics problems often encountered in earthquake engineering practice.
