贵州地区某天主教堂抗震及加固设计研究

Research on Seismic and Reinforcement Design of a Catholic Church in Guizhou Province

本文重点介绍贵州地区某天主教堂砖混结构的抗震分析与加固设计。经检测,建筑使用过程中,教堂大门洞口位置左上角出现超过5mm裂缝,教堂大门正对后侧墙体出现通长的竖向裂缝,采用YJK分析抗震弹性计算结果,根据检测及计算结果选用最优的加固设计方案。通过对关键构件进行加强措施,以保证关键构件满足良好的结构整体性及抗震性能要求。此外,本文系统介绍了既有砌体结构建筑安全性检测鉴定的流程,针对上述建筑缺陷及抗震不足提出的加固方案,经济简单奏效,旨在为解决其他类似的工程问题提供参考。

This article focuses on the seismic analysis and reinforcement design of a brick concrete structure of a Catholic church in Guizhou region.After testing,it was found that during the use of the building,a crack exceeding 5mm appeared in the upper left corner of the church gate opening,and a full-length vertical crack appeared on the wall directly opposite the church gate.YJK was used to analyze the seismic elastic calculation results,and the optimal reinforcement design scheme was selected based on the testing and calculation results.By strengthening measures for key components,it is ensured that they meet the requirements of good structural integrity and seismic performance.In addition,this article systematically introduces the process of safety inspection and appraisal for existing masonry structures,and proposes reinforcement plans for the aforementioned building defects and seismic deficiencies.It is economical,simple,and effective,aiming to provide reference for solving other similar engineering problems.
