以某校综合楼加层改建设计为例,论证了框架结构房屋加层改建工程的三种常见方法,引入一种有效的混合结构梁柱节点连接方式。经设计、计算、施工证明,此加层方法简单易行、工期缩短、效益明显,对同类工程的加层有借鉴意义。 Taking a school complex building as an example, this paper demonstrates three common methods of adding structural alterations to the frame structure houses, and introduces an effective connection method of beam - column joints with mixed structure. The design, calculation, construction proved that this method is easy to add layer, shorten the period, the obvious benefits, for similar projects have additional reference.
