Research work in this paper includes inelastic analysis of earthquake responses of single-story factory buildings with roofs continuing to act as a whole unit under seismic action. In case the building is made up of spans with roofs at different levels, then each roof system is taken as a horizontal rigid diaphragm with its mass concentrated at its center of gravity. Therefore, there are three degrees of freedom (two transla-tional and one rotational) corresponding to every mass.According to the above model,...

Research work in this paper includes inelastic analysis of earthquake responses of single-story factory buildings with roofs continuing to act as a whole unit under seismic action. In case the building is made up of spans with roofs at different levels, then each roof system is taken as a horizontal rigid diaphragm with its mass concentrated at its center of gravity. Therefore, there are three degrees of freedom (two transla-tional and one rotational) corresponding to every mass.According to the above model, a computer program was developed for the investigation of inelastic earthquake responses of equal-height or unequal-height multi-span single-story factory buildings subjected to ground motion in one or two directions.

This paper discusses the hysteresis characteritics and ductility of R. C. compression-flexure members under cyclic loading. Investigations were made through 32 specimens tests on the effect of different axial loading ratios, stirrup, and longitudinal steel reinforcement contents. Test results show that the effect of slip of bond at joint region on the deformation and hysteresis characteristics of the R. C. members is significant and should not be neglected. A model for bound restore is proposed here for the...

This paper discusses the hysteresis characteritics and ductility of R. C. compression-flexure members under cyclic loading. Investigations were made through 32 specimens tests on the effect of different axial loading ratios, stirrup, and longitudinal steel reinforcement contents. Test results show that the effect of slip of bond at joint region on the deformation and hysteresis characteristics of the R. C. members is significant and should not be neglected. A model for bound restore is proposed here for the nonlinear analysis of R. C. structures upon seismic response. The regularity of the hysteresis loops of the moment-curvature relationship is discussed. The load-deflection hysteresis loops of the members are calculated and compared with the measured results, showing good agreement.

本文讨论了钢筋混凝土压弯构件在周期反复荷载作用下的滞回特性及其延性,研究了轴压比、箍筋率和纵向配筋率对这些特性的影响。通过三十二根试件的试验结果表明,伸入节点区钢筋的粘结滑移对构件的变形及滞回特性具有显著的影响,不容忽视。本文提出了可供结构非弹性地震反应分析用的钢筋粘结滑移恢复力模型,并对截面弯矩与曲率关系的滞回规则作了讨论。文中还对构件的荷载一位移滞回曲线进行了理论计算,并与试验结果作了比较,两者吻合较好。

A nonlinear elastic-viscoplastic constitutive relation is used to simulate the dynamic behavior of metal structural meterials. A finite element formulation for inelastic earthquake response analysis of shear space frame structures considering horizontal-torsional coupling vibra- tion is developed. The plastic yield condition of frame column is rep- resented in stress resultants. The need to determine the state of ele- ments either elastic or plastic and to verify either loading or unload- ing cccuring at each step in usual elasto-plastic dynamic analysis is eliminated. P-△ effect ■s taken account in constitutive relation of column element. An implicit second-order Runge-Kutta scheme in conj- uction with a Newton-Raphson iteration technique is used for sovlving nonlinear equations of motion.

用非线性的粘——弹——理想塑性的本构关系来模拟金属结构材料的动力行为,导出了剪切型框架结构平扭耦联非弹性地震反应分析的有限元公式。用广义应力表达了框架柱的塑性屈服条件。计算过程中取消了在通常的弹塑性动力分析中,每一步长内都要确定每个单元是处在弹性状态,还是塑性状态,以及判别是加载还是卸载过程的要求。导出柱单元本构关系时计入了“P-△”效应的影响。用隐式的二阶Runge-Kutto法和Newton-Raphson迭代法相结合来积分非线性的运动方程。
