At the present time, in Japan, steel that can be used in concrete encased [ designated as SRC ] structures is limited to 53 kgf/mm^2 and concrete is limited to 360 kgf/cm^2 in strength, but use of steel and concrete having a higher strength has been expected to construct SRC structures higher, more economical and also more flexible in structural planning. In order to promote the use of high strength steel and concrete in SRC Structures, a three year comprehensive research was conducted. This report presents the background and objectives of the project, out line of the test programs and major results obtained from the individual tests. This report also proposes design procedures effective to the design of SRC Structures with high strength steel and concrete. To obtain the general information on the compression, flexure and shear behavior in the inelastic range of SRC columns with high strength steel and concrete, a parametric experimental study was carried out on the strength, deformability, failure mechanism, and hysteretic characteristics under reversed cyclic loading using 51 column specimens. Major variables chosen for the series of tests were steel materials ( HT60, SM590A ), concrete materials ( normal concrete sigma_B = 300 kgf/cm^2, high strength concrete sigma_B = 600 kgf/cm^2 ), steel section, hoop materials, the amount of hoop reinforcement and the magnitude of axial compression load. Furthermore, theoretical procedure is developed for calculating the ultimate compressive, flexure and shear strength of SRC columns using high strength steel and concrete. For the compressive, flexure and shear strength of SRC columns with high strength steel and concrete, the superposed strength method is applicable if steel does not exceed to 60 kgf/mm^2 and concrete does not 600 kgf/cm^2 in ultimate strength.

目前，在日本，可用于混凝土包裹结构的钢的强度限制为53 kgf/mm ^2，混凝土的强度限制为360 kgf/cm ^2，但人们期望使用具有更高强度的钢和混凝土来建造更高、更经济且在结构规划上更灵活的SRC结构。为了推广高强钢和高强混凝土在型钢混凝土结构中的应用，进行了为期三年的综合研究。本报告介绍了该项目的背景和目标，概述了测试程序和从各个测试中获得的主要结果。本报告还提出了有效的设计程序的SRC结构的设计与高强度钢和混凝土。为获得型钢高强混凝土柱在非弹性范围内的抗压、抗弯和抗剪性能，对51根型钢高强混凝土柱在低周反复荷载作用下的强度、变形、破坏机理和滞回特性进行了参数试验研究。试验选取的主要变量为钢材（HT 60、SM 590 A）、混凝土材料（普通混凝土σ_B = 300 kgf/cm ^2、高强混凝土σ_B = 600 kgf/cm ^2）、型钢、箍筋材料、箍筋配筋量和轴压荷载大小。在此基础上，建立了高强型钢混凝土柱抗压、抗弯、抗剪承载力的理论计算方法。对于高强型钢混凝土柱的抗压、抗弯、抗剪承载力，当型钢极限强度不超过60 kgf/mm ^2，混凝土极限强度不超过600 kgf/cm ^2时，可采用叠加强度法。
