Development of Structural Design Procedure of Buildings Harmonizing Damage Control Seismic Design and Fire Design Based on Constitutive Laws of Materials and Deformation Analyses

研究了作为建筑结构材料的钢和混凝土在高温下的使用，以设计不倒塌的建筑结构，并预测在火灾中和火灾后对结构构件的损伤。在实验和数值分析的基础上，对这些材料的应力应变关系和粘结滑移关系进行了理想化。梁-柱组合在高温下进行了测试。将计算结果与数值分析结果进行了比较。提出了一种新的梁柱组合件的小炉子试验方法。最后，通过试验和分析研究了裂缝对钢筋混凝土构件温度分布的影响。

Steel and concrete as structural materials used for buildings were investigated at elevated temperatures, to design building structures not to collapse, and to predict damage on structural members during and after fire. Stress - strain relationships of these materials, and their bond - slip relationships were idealized on the basis of experiments and numerical analyses. Beam - column assemblages were tested at elevated temperatures. The results were compared with the numerical analysis ones. A new test method using a small furnace was developed for a beam-column subassemblage. Finally, an influence of crack on temperature distribution in reinforced concrete members was experimentally and analytically studied.
