【摘要】 在我国产石地区,石砌体结构是一种传统的结构形式,具有独有的特色和极佳的特性,倍受人们的青睐。由于材料特性和施工原因,致使结构整体性差、抗震性能弱,震害严重。提出约束石砌墙体承重结构概念,分析其抗震性能,建立抗震抗剪强度验算公式,提出约束石砌体结构抗震能力的模糊安全准则及其可靠性验算方法。经实例应用,方法简易可行,公式概念清晰,符合现行设计理论;经约束后的石砌体结构抗震可靠度有较大提高,抗震性能显著改善;扩展了石结构的应用范围,可供其它砌体结构的抗震设计和加固等参考。更多还原

【Abstract】 In regions with abundant stones, stone structure is usually used. It is favorable with its unique features and good characteristics. However, its earthquake resistant capacity is low due to its poor structural integrity, with severe earthquake damage because of its material characteristics and construction methods. The concept of restrained stone masonry bearing structure is proposed. The earthquake-resistant behavior of the structure is analyzed, and formulas for earthquake resistant strength and shear strength are presented. Fuzzy safety criterion of earthquake-resistant capacity and the reliability calculation method are also proposed. It is demonstrated with examples that the methods are simple, and the formulas are distinct and accord with the design theory in operation. The earthquake-resistant capacity can be increased considerably. The methods can be used as references for the earthquake resistant design of other masonry structures.更多还原
