某框架结构的抗震性能检测分析

Seismic Performance Test and Analysis of a Frame Structure

摘要: 介绍了某框架结构进行抗震性能检测分析。针对该框架结构的抗震性能分析，主要进行三方面工作。通过进行房屋现状调查来了解结构的使用及破损情况，通过抗震构造调查来了解结构的抗震体系及构造措施，通过PKPM系列软件对该建筑进行抗震承载能力验算。结果表明：1) 设计不合理，结构体系不利于抗震，构件设计承载力不满足抗震要求，是导致结构不满足抗震要求的主要原因；2) 施工质量不达标，导致预制板拼接处出现裂缝，构件尺寸与设计不符，箍筋间距不满足要求，是结构不满足抗震要求的次要原因；3) 建议优化结构体系，改变结构受力方式，同时对主要受力构件进行加固，修补结构裂缝。

Abstract: The seismic performance of a frame structure is analyzed. According to the analysis of the seismic capacity of the frame structure, three aspects are mainly carried out. Through the investigation of the current situation of the building, the use and damage of the structure are understood. The seismic system and structural measures of the structure are understood through the seismic structure investigation. The seismic bearing capacity of the building is checked and calculated by PKPM series software. The results show that: 1) due to unreasonable design, the structural system is not conducive to earthquake resistance, and the design bearing capacity of components does not meet the seismic requirements, which are the main reasons for the structure not meeting the seismic requirements; 2) the construction quality is not up to the standard, which leads to cracks at the joints of precast slabs, the size of components does not conform to the design, and the stirrup spacing does not meet the requirements, which are the secondary reasons for the structure not meeting the seismic requirements; 3) it is suggested that the structural system should be optimized, the stress mode of the structure should be changed, and the main stress components should be strengthened to repair the structural cracks.
