摘　　要：高雄市立图书馆,地上结构以位于四角的巨型柱与第8层的巨型桁架层组成巨型框架作为主要抗侧力及竖向力系统,并利用钢材受拉最有效率的设计原则,采用高张力钢棒悬吊3楼至7楼的楼板,有效减小柱截面尺寸,实现了地面层的无柱开放空间。地下部分以经济性最好的钢筋混凝土梁柱构造加上筏式基础。该工程为悬吊式结构,故施工顺序是先完成巨柱及顶部桁架层,再自上而下建造,有别于传统建筑工法。该工程在完工后还针对整体结构及楼板作微震测量,以考察理论分析和实际建筑物的振动频率差异,及楼板振动的舒适性。Kaohsiung Pubic Library is supported by four corner mega columns and a one-story high mega truss at eighth floor level,forming both vertical and lateral-resisting systems.The third to seventh floor plates are suspended by highstrength tension rod connecting to the truss level of roof top.The structure performs the most efficient way of steel structure by subjecting to tensile force transference,and thus creates a visually column-free space at typical floor and a maximum open space at ground level.The basement structure is reinforced concrete frame and mat foundation.The conventional construction method is based on the ground level,and its constructional sequence is from bottom to top.Instead of conventional way.Kaohsiung Pubic Library is designed as a suspended structure.Based on the roof-truss level,the construction sequence is from top to bottom.In addition,tests and analysis of micro-vibrations are adopted to verify the difference between analysis and reality,and to confirm the serviceability against floor vibrations.
