摘要
通过托梁拔柱实现某工程对大空间的使用要求,将体外预应力和增大截面加固综合应用于抽柱后形成的大跨度梁上,同时对周边框架柱进行了常规加固处理,保证了结构安全度,为同类工程改造设计提供了参考。
By strengthening beam for removing requirements, the external prestressing and increase span beam with demolishing conventional processing, which column using a project on the large space cross-section reinforcement are used in a long column, while the surrounding ensures the safety of structure frame columns are reinforced by and provides a reference for similar engineering design.
