摘要
多层砌体房屋顶层空旷少墙时,该层地震剪力可能较大。本文以振型分解反应谱抗震计算方法和结构振动理论为基础,探讨这种情况时地震作用的某些规律,给出顶层地震剪力上限值的实用计算方法。
When the top floor of a tier masonry is more soft than the rest, the seismic response in this floor may be greater. Based on mode superposition response spectrum method and structural vibration theory, upside soft tier masonries were studied, some traits of seismic response for this kind of buildings were proposed, and also, a practical method of seismic response′s maximum in top floor for upside soft tier masonry is given.
