| 中文摘要: |
| 对某既有多层框架结构抽柱托梁大跨度改造，在一至三层拆除双向8.5m柱网的框架柱，形成25.5m跨3层高的大空间，创新性采用组合梁+钢斜撑的空间复合结构体系，在MIDAS整体分析的基础上，作为隔离体使用ABAQUS有限元分析，并和实时监测数据验证，可供类似工程参考。 |
| 英文摘要: |
| For the large-span reconstruction of an existing multi-storey frame structure by pulling out columns and supporting beams, the frame columns with two-way 8.5m column grid are removed from the first to third floors to form a large space with a 25.5m span and three floors. The space composite structure system of composite beams and steel diagonal braces is innovatively adopted. On the basis of the overall analysis of MIDAS, ABAQUS finite element analysis is used as an isolator, and it is verified with real-time monitoring data, It can be used as reference for similar projects. |
