强地震下不同建筑结构形式房屋受损研究

Damage Research on the Different Structure Buildings under the Intense Earthquake

5.12四川汶川特大地震发生后,灾区很多建筑房屋受到不同程度地损坏。探讨强地震对不同建筑结构型式房屋的影响和损坏程度,以便为灾区重建提供科学依据。结合到灾区对震后房屋进行检测的数据,将不同结构型式的房屋在强地震后的损坏情况进行分类分析。利用结构力学原理研究了房屋损坏的原因和规律。针对5种建筑结构形式的受损房屋和受损楼梯间,提出了不同的修缮和加固建议。

After the intense earthquake happened at Wenchuan in 5.12, many buildings have been damaged at different degree in disaster area. In order to research the damage of the different structure buildings under the intense earthquake, the different structure buildings are classified and analyzed. Then, the damage characteris- tics of buildings are obtained. These conclusions can help to reconstruct buildings in disaster area. In view of the damage data of buildings checked and measured after intense earthquake, the damage reason and the damage regulation of the buildings are studied using the structure mechanics theory. At last, according to five structure buildings and staircase, the different advice of remedy and reinforce are proposed.
