某图书馆加固设计分析

某图书馆为3层框架结构。由于用途发生改变,2层的会议室须改造为密集书库,经验算发现局部板和梁的承载力出现不足。对板分别采用粘贴碳纤维、增设钢梁以及增加板厚这三种方法进行加固,得出最经济适用的方案。对承载力不足的大部分梁采用粘钢法加固,局部超筋梁采用增大截面法进行加固,取得良好效果。

The Reinforcement Design Analysis of One Library

One library is a frame structure that has three layers.Because of the function changes,the meeting room on the second floor needs to be converted into densely stack room,it turns out that bearing campacity of local beams and floorslabs can＇t meet the needs after check calculation.Sticking carbon fiber,setting steel beam and increase of the thickness of plates are respectively used to reinforce the floorslaps,the most economical plan is tried to be found.Most of beams with insufficient bearing capacity is strengthened by sticking steel method,several overreinfoced beams is strengthened by enlarging section area method and achieve a better effects.
