Discussion on the Key Technical Problems in the Design of a Double-Tower Structure with Large Chassis
The multiple-tower structure with large base is a vertical irregular structure,which might be damaged seriously under strong earthquake.Taking a high-rise residential structure with large chassis and double towers without seam as the research object,PKPM soft-ware is used,and the structural integrity and seismic performance are emphatically analyzed,the corresponding strengthening measures of aseismic structure for the weak parts of the structure are put forward.The results show that the structural scheme is feasible without deform-ation joint between the tower and the annex,and strengthening measures must be taken for the weak structure in the sudden change area of upper and lower floors and vertical members.The results can be used as reference for similar engineering design.
