Technical Economy Comparison Analysis of Steel Beam Connection Types for Super High-Rise Hybrid Structures
摘要
Abstract
Comparing study for the effect of steel floor beam connection types on the structural behavior, construction time needed and cost of hybrid structures with strengthened story is conducted based on an actual project of 52-storey and 224. 8 m high. The result shows that steel beams should be pinned at both ends or pinned with concrete core and rigidly connected with perimeter frame columns in super high-rise hybrid structures. Outrigger of strengthened story may work together with concrete core tube, being part of a new lateral load resisting system of outrigger-core tube. Scheme of pinned connection at both ends can save the cost about ten percent than rigid connection one.关键词
