摘要
Abstract
The invisible beam-column reconstructed method has been put forward for the study of old masonry buildings' seismic performance analysis.Three selected structure models of the experiment are:Masonry structure model with no ring beams and constructional columns,masonry model with ring beams and constructional columns and masonry structure model of invisible beams.Modal analysis and seismic response process analysis of each group were carried out,and inter-vibration period,structural damage,the maximum horizontal displacements,story drift,and earthquake acceleration values were compared.Under earthquake action,the acceleration value of no ring beam structure is maximum,followed by is invisible beam column structure,and the ring beam structural is minimum.The smaller the acceleration,the lower the damage extent on the structure.The research indicates that the invisible beams method improves the integrity and energy dissipation capacity of structures,thereby improving the seismic capacity.关键词
