ANALYSIS ON STORY LATERAL STIFFNESS RATIO AND SHEAR CAPACITY RATIO OF COMPLETE FRAME-SUPPORTED SHEAR WALL STRUCTURES
During the service of transportation,sudden change to the height of vehicle base's ground floor leads to the significant variation of stiffness and shear capacity in complete frame-supported shear wall structure,which sub-stantially exceeds the standard.After the discussion on the calculation methods for lateral stiffness and shear capaci-ty in current code,we analyze the mechanic characteristics of bottom frame in complete frame-supported shear wall structure under horizontal loads,indicating the calculation methods above are inapplicable on complete frame-sup-ported shear wall structure.It suggests that,in the precondition when upper shear wall yield before bottom frame structure,lateral stiffness ratio and shear capacity ratio of first and second floor are not necessary to satisfy the speci-fication.
