Multi-tall steel structure system selection and design
Now the construction of multi-level home country for the selected steel structure construction system is divided into four categories:
1) pure construction methods;
2) construction of the support methods;
3) The combination of steel reinforced concrete;
4) steel-concrete seismic wall constructed way.
On pure construction method, material selection steel beams, welded or bolted through mode can be combined installation. Construction of the support structure similar to the way the same way as pure, just because seismic needs, in the direction of the body structure are arranged two spindle bracing, steel bracing and the type of steel columns and beams connected to form the vertical lateral force resisting truss to replace traditional concrete shear wall, install the same way as the choice of welding or bolting. Features SRC combination is outside the steel skeleton of beams additional layer of concrete pouring, pouring new concrete structure not only play a role, while helping to solve the main structure of the anti-corrosion, fire issues.

Steel-concrete seismic wall constructed way, external beam-column systems use steel, the same way after welding or bolting combined installation, use cast construction methods or the inner core tube wall, through the embedded member with peripheral steel structure construction phase connection, together constitute the 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 stiffness and ductility difference between the more, now the main residence of choice in high-rise steel structure low-intensity earthquake zone. Steel structure residence should be designed according to safe, reliable, economical, convenient construction principles, combined with the construction of the use of function, construction, maintenance and construction of the module structure and seismic intensity seismic requirements reasonable based on merit and good wind performance structural system to ensure the structure has sufficient wind, seismic capacity and features to meet the residence application functionality.
