Steel Tube Confined Concrete Structure And Its' Limitation Analysis

With the quick boom of economy and the rapid development of construction, modem buildings call for better and better material than before. Steel Tube Confined Concrete(STCC) has been applied in building widely and has acquired economic benefit largely for its excellent quality in structure of big span, height, and loads, good quality of behavior in bad environment, fine gift in industrialization produce. So, it' s a good material of building. Firstly, this paper describes theoretical formula through analysis some behavior in loads of axial compression, draught, bend and part compression. Then pays attention to analyses limitation of material and effect of this limitation, summarize bad influence of unqualified perfusion on material behavior. Finally, a feasible dumbbell-shape STCC bridge' s construction plan is summarized through analysis the special project accident. This paper aims to show reader STCC' s basic behavior, limitation and some problem from this material using in project. To make designer and builder know deeply about this material is the author' s biggest wish.
