［摘要］通過理論分析和實(shí)際工程數(shù)值計(jì)算研究了高層建筑地下室樓板模型及地下室外回填土約束作用對核心筒剪力墻計(jì)算結(jié)果的影響。研究表明，地下室樓板采用剛性假定不能真實(shí)地反映結(jié)構(gòu)的受力狀況，無論地下室外回填土的約束作用是否考慮，都會得出地下１層墻肢剪力突增的計(jì)算結(jié)果；而地下室樓板采用彈性殼元模擬，即便地下室外回填土的約束設(shè)定為無約束和水平剛性約束兩種極端情況，地下1層核心筒剪力墻依然不會出現(xiàn)顯著的剪力突變。

Abstract:The effects of the basement floor model and restraint from backfill soil on the calculation results of core tube shear walls were studied theoretically and numerically. The rigid floor assumption could not reflect the actual bearing conditions, and shear mutation of core tube shear walls located on first basement was obtained independent of the backfill soil. When basement floors were modeled by elastic shell elements, there would not be shear mutation in mentioned positions even if the restraints from backfill soil are modeled without lateral restraint or with lateral stiff restraint.

Keywords:shear wall; shear mutation; rigid floor assumption; elastic floor assumption; restraints from backfill soil
