中文摘要: |
为进一步理解汶川地震中一些钢筋混凝土框架结构的破坏原因,根据汶川地震后框架结构震害调查资料,对照《建筑抗震设计规范》所规定的抗震设计原则,对框架结构中的一些典型震害现象及其产生原因进行了总结与分析,主要包括防震缝处的震害,结构竖向刚度、强度不均匀产生的震害,框架梁、柱及节点处的震害,围护结构与填充墙处的震害及楼梯震害.在对震害现象及其产生原因详细分析的基础上,给出了加强框架结构安全性的措施.所得分析结果可为框架结构抗震设计及有关的规范修订提供参考,以保证框架结构在地震中达到“小震不坏,中震可修,大震不倒”的三水准设防目标. |
英文摘要: |
To further understand the reasons of the damage of reinforced concrete frame structures during Wenchuan earthquake, some typical damaged appearances of frame structures are summarized and the reasons of damage are analyzed according to the rules described in the Code for Seismic Design of Buildings, including the damages around the aseismic joint, damages due to uneven distribution of stiffness or strength along vertical direction, damages in the beams, columns and nodes of frame structures, damages of enclosed walls and stairs. Based on the analysis results, some methods to enhance the safety of frame structures are proposed. The research results can provide a reference for seismic design of frame building structures and revision of corresponding codes and regulations so that the frame structure can achieve the seismic protective objective of undamage for small earthquake, repairable damage for moderate earthquake and uncollapse for severe earthquake. |
