前几天做一工程，周期比总是稍微高于规范一点。想了半天也没有一个很好的办法。后来查阅资料和实验性计算发现，对结构周边梁加强，减少结构中部柱、墙刚度，加大端部构件刚度很有效。不知大家有何高策，一起学习哦！

我做的小高层没有碰到类似情况
我做的小高层最多的是框架结构，暂且没有碰到过
学习中，谢谢各位前辈赐教

周期比超限就说明结构的抗扭刚度较小,因此减小结构中部构件刚度,加强结构周边构件刚度就最有效的办法,另外质心与刚心距离相差太远也有较大影响,应尽量调整使刚心与质心距离不要太大.周期比过大，说明了结构刚度分布不均匀偏心过大。需要调整结构的刚心，1~3楼所说的是一种方法，即增大周边结构的刚度从而增大结构整体抗扭刚度。当然，增加梁高往往会受到建筑功能的限制，有时是无法实现的。这种情况下可通过调整结构布置减少刚度偏心的方法

小弟也是这样去做的，增加周边构件刚度效果很明显
但是刚心和质心离得太远也有问题！

按对称均匀的原则,增加周边的刚度,减小中间的刚度,整个结构尽量均匀对称.一般情况下能満足规范要求的

增加周边 然后减小内部 主要的调整方法是增加结构的抗扭刚度 直有反复的调试才可以 努力吧
