［摘要］毕节金海湖新区文化“三馆一中心”由图书馆、文化馆、展览馆、演艺中心四个单体组成，四个单体采用钢筋混凝土框架体系，单体之间通过钢连廊相连。结构存在扭转不规则、平面大开洞、竖向收进、大底盘双塔、穿层柱、夹层、构件转换等不规则情况。对各种不规则情况采取了相应计算分析和构造措施。对钢连廊在大震下的支座滑动位移和在人群行走相位不一致情况下的舒适度进行了详细计算。计算结果表明，结构各项指标均能满足规范要求。

Abstract:Three cultural venues and one theater of Jinhai Lake New District in Bijie consists of a library, a cultural center, an exhibition center and a theater. The four structures are reinforced concrete frame system, and the structures are connected by steel corridors. There are some irregularities in the structure, such as torsion irregularity, large planar opening, vertical indentation, large chassis double tower, cross-layer column, interlayer, component conversion and so on. Corresponding calculation analysis and structural measures were taken for various irregular situations. The comfort degree of the steel corridor was calculated in detail under the condition that the sliding displacement of the support and the walking phase of the crowd were not the same. The calculation results show that all indexes of the structure can meet the requirements of the code.

Keywords:transfinite high-rise building; corridor; sliding bearing; vibration comfort
