摘要: | 本研究旨在探讨钢骨钢筋混凝土(SRC)构造之耐震与韧性设计等相关 问题。本研究首先 针对美国及日本等先进国家最新之SRC耐震设计相关规 范进行比较与探讨,经由系统化的交 互比较分析,得以发现各规范在SRC 构材耐震设计及梁柱接头构造细则方面规定之特色及优 缺点,以作为国 内未来研拟SRC耐震设计规范之参考。 另一方面,本研究针对包覆 型SRC梁之耐震弯矩强度进行探讨,研究结果显示本文所提 出的“直接强 度叠加法”可以合理的评估包覆型SRC梁之耐震弯矩强度。再者,本研究 亦针 对“刚度分配法”在SRC梁柱构材剪力设计之应用提出新的设计方法 。此外,本研究根据 SRC柱中钢骨翼板与腹板对混凝土围束效应的贡献, 探讨包覆型SRC柱围束箍筋与梁柱接头区 剪力之设计,研究结果发现本文 所建议之设计方法将可得到合理之设计结果。最后,本研究 更进一步针 对耐震设计中SRC构造之韧性容量因子(R值)作系统性之探讨,并尝试提出 相关的 SRC构造R值评估公式,将有助于合理的估算SRC构造之韧性容量。 综合言之,本研究除了对目前各先进国家有关SRC构造之耐震设计规定作 系统性的深入比 较探讨之外,亦针对SRC梁柱构材耐震韧性设计及梁柱接 头区剪力设计与SRC构造之韧性容量 等问题,提出相关之建议与新的评估 方法,期望本研究之结果能对SRC构造耐震设计之品质提 升有所助益。 This research is devoted to the investigation of the earthquake resistant design of steel reinforced concrete (SRC) composite structures. An extensive literature survey was first conducted towards the state-of art design specifications of the U.S.A., Japan and other countries. Then, a systematic comparative study on the design rules of SRC members and detailing of beam-column joints among these specifications was made. It is intended that this comparison will provide some useful suggestions for the development of a new seismic design code of SRC structures in Taiwan. In addition, a study on the earthquake-resistant bending capacity of encased SRC beams is presented. A new method using the direct superposition approach is proposed, which shows satisfactory results as compared to the values predicted by other existing methods. In the meanwhile, a new design approach is proposed for the shear design of SRC members based on the concept of rigidity distribution method. In addition, this study attempts to investigate the design of lateral ties in concrete encased columns and the shear design of beam-column connection panels, the concrete confinement effect provided by structural steel web and flanges is considered in this study. It is found the results obtained from the proposed method are satisfactory. Finally, this study also presents a new set of equation to evaluate the structural ductility factor (response modification coefficient, R) of SRC buildings, which provides a rational basis for the determination of the R val ues to be used in the seismic design practice. |
