Multi-tall steel structure system selection and design

Multi-tall steel structure system selection and design

At present, the construction of more homes were tall steel structure of the selected primary structural system is divided into four categories:
1) Pure framework approach;
2) frame supporting method;
3) a combination of steel reinforced concrete method;
4) steel frame a concrete wall seismic methods.
For pure frame method, steel beams material selection, Hainan combined installed steel welded or bolted through the convergence approach. Frame support framework approach similar method with the pure, just because seismic needs, in the main structure arranged two spindle direction bracing, steel bracing and type of vertical steel columns and beams convergence constitute lateral force resisting truss to replace traditional concrete shear wall, installation method also choose welded or bolted convergence. Featured steel concrete composite method is outside the steel skeleton beams pouring additional layer of concrete, pouring new concrete structure not only play the role, while helping to solve the main structure of the anti-corrosion, fire questions.
Steel frame of a concrete wall seismic method, the external system used steel beams, the same combination installation by welding or bolts convergence method, the inner core tube or shear cast chosen method of construction, through embedded member with the same peripheral steel frame construction convergence, constitute structural system. This amount of steel structural system is less than pure steel structure, construction speed between pure steel structure and concrete structure. But steel and concrete material difference between the more stiffness and ductility, currently the primary choice in high-rise steel structure residence low-intensity earthquake zone. Steel structure residence should be designed according to safe, reliable, economical, convenient construction principles, combined with the use of functional architecture, building blocks and building maintenance structure and seismic intensity seismic requirements reasonable based on merit and good wind performance structural system to guarantee structure with sufficient wind, earthquake shelter to meet the characteristics and use of the function.
