汶川地震对远震区高层建筑造成的震害及设计建议
|
摘要
"5·12"汶川大地震的震级达到了里氏8.0级,该次地震对远震区高层建筑造成了不同程度的震害.通过对西安市区高层建筑的震害进行介绍和总结,分析了远震区高层建筑的震害特点和原因,并分别从地震作用水平和抗震设防水准、防震缝的设置、填充墙的设置等方面,对高层建筑的抗震设计和抗震措施提出了建议.
With a magintude of 8.0,wenchuan Earthquake caused different degree seismic damage on high buildings in the areas remote from epicenter.Based on the introduction and sum-up of the seismic damage of high buildings in Xi′an City,the seismic damage characteristic and reason of high buildings in the remote areas from the epicenter zone are analyzed.Then several suggestions about a seismic design and measures are given,including the earthquake hazard level and a seismic fortification level,the disposal of quakeproof slot and filled walls.
