摘　　要：采用非金属超声波测试仪对受力后的外肋环板(VS)和隔板外伸(TD)柱节点进行探测,研究了钢管与混凝土之间的缝隙情况;通过切割破损试验指明了缝隙的存在,验证了叠加法计算方矩型钢管混凝土柱承载力的理论基础,表明了该方法简明、可靠且适用于实际工程设计.Through the test of Concrete-filled Rectangular Tubular (CFRT) of TD and VS by nonmetal Supersonic Flaw Detecting Apparatus, the status of gap under the exterior forces is analyzed. Through the incision test, it show that the gap really exist and prove that the theoretical foundation of simple Superposition Calculation is accurate and reliable for bearing capacity calculation of Concrete-filled Rectangular Tubular in practice engineering.
