摘要
在分析医疗建筑结构设计特点的基础上,提出宜在设备层以下增设混凝土墙来解决由于设备层层高较低而出现的侧向层刚度比超限的问题。针对临汾新医院住院楼工程细腰形平面的不规则性,运用PMSAP软件对结构做了详细分析计算,将规范对细腰处楼板"加大厚度"的模糊要求数值化,同时指出在细腰处的凹角部位增设端柱可有效降低应力集中,减轻震害。
On the basis of the characteristic of medical architecture structural design,the problem,that the ratio of story lateral stiffness is beyond the limit for the lower equipment layer was solved.The solution is to add concrete wall below the equipment layer.Because of the irregularity of thin-waist shape of Linfen New Hospital building,the structure was analyzed and calculated by PMSAP software.Numerical value of faintness requirement ＇increase thickness＇ in codes for the thin-waist shape floor was provided.Meantime,the advice that adding end column on the nook of the thin-waist to reduce stress and lighten earthquake action was put forward.
