NUMERICAL SIMULATION OF MASONRY STRUCTURE SUBJECTED TO EARTHQUAKE
-
摘要: 对砖混结构裂缝进行分析,给出结构刚度矩阵形成方法,利用有限元方法,模拟出墙体在地震作用下裂缝逐渐开展直至墙体完全破坏,从而分析出结构在大震情况下结构振动和破坏特性。方法同样可以应用于其他脆性材料的结构。Abstract: The formation of a rigid matrix is given by analysing crevices of a masonry structure.It is simulated that the walls collapse for increasing cracks in walls under action of earthquake by FEM,and the characteristic of vibration and collapse in the structure is concluded.The method given in the paper can also be used in other structures made of brittle materials.
