| Research Abstract |
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.
