<input id="uauy4"></input> What are the advantages of steel frame structures?
1, Foshan Steel seismic function well: Because steel ductility, both weakened earthquake response, but also makes the steel resistant to intense earthquake deformation capacity;
2, light weight: the ability to significantly reduce the structural foundation of the vertical load transmitted and seismic effects;
3, the full use of building space: Since the column section is small, increase the area of the building using 2-4%;
4, short construction period, creating fast;
5, constitute a larger space, flexible layout, structure, each part of a more uniform rigidity, simple structure, easy construction;
6, lateral stiffness is small, the effect of horizontal loads in the second-order effects can not be ignored; due to lateral displacement of large earthquakes, causing damage to non-structural components.
There is a fire-resistant function is poor: the steel beams, columns, bracing and used for load-bearing pressure plate and other requirements by spraying fire retardant paint. Damage to draw lessons to improve steel design: Due to the complexity and randomness of the actual earthquake engineering, it is difficult to avoid the cracking of nodes, such as the support of buckling damage.
