Establishment of Structural Performance Evaluation Method for A New Composite Building Structural System (CES)

为使混凝土外包钢结构作为一种新型的长期耐久性建筑结构体系得到实际应用，进行了CES柱、带楼板的CES框架和CES剪力墙的结构试验。试验结果表明，CES构件具有良好的抗震性能，具有较高的强度、延性和损伤控制效果。根据试验结果，提出了CES构件强度、变形性和恢复力特性的评价方法。在此基础上，提出了基于反应极限强度法的CES建筑结构性能评估方法。

For the purpose of practical use of the composite CES (Concrete Encased Steel) structure proposed as a new building structural system of the long-term durability type, structural tests on CES columns, CES frames with floor slab and CES shear walls were conducted. It was clarified from the tests that the CES members have good seismic performance with high strength, ductility and damage control effects. The evaluation methods of the strengths, deformability and restoring force characteristic of the CES members are proposed based on the test results. Furthermore, the evaluation method for structural performance of CES buildings using the response and limit strength method is proposed.
