某大开洞办公楼结构设计的分析

Analysis of Structural Design of a Large Open Hole Office Building

摘要: 某办公楼由于采光需要而采用中间开两个大洞的“日”字形平面，从而引起结构周期比超限、结构梁柱截面过大等问题。本文采用钢框架结构体系与钢框架支撑结构体系，利用PKPM计算分析软件，通过结构性能化设计、方案的对比，确保在建筑使用功能、结构安全前提下，结构综合经济指标的合理。

Abstract: One building with two huge holes, which consider for lighting, causes the structure problems of structural period ratio, and structural beam-column section is large. This building was designed as steel frame system and steel frame-brace structure. By using the software of PKPM, the compre-hensive economic indicators of structures are reasonable, through structural performance design and comparison of the schemes, ensuring functional and structural safety of the building.
