Vertical Load-bearing Performance Research Of Light Steel Board-rib Wall

Lightweight steel stucture residence is one kind of steel stuctures technique, which has been adopted widely in outside world as a kind of architecture form and just has been developed laterly in our country these years. Depending on the whole series of technique and building material product line of Occident countries, most of domestic corporations product and assemble the residences at home. Because of the existing obvious differences between the building codes in overseas and that in civil, it is quite necessary for us to reserch the load bearing performance of this stucture in theory and experiment aspect.This article introduces and compares the calculation mode of section valid width in Amercian "Cold-Formed Steel Structural Member Design Code" and in civil "Cold-Formed Steel Structural technique Code". And introduces the carrying capacity calculation formula and diverse destructive modes of the steel stud with same surface board linked on both side edges under vertical load in Amercian "Cold-Formed Steel Structural Member Design Code", and validated the conclusion with contrast experiments by single steel studs and steel studs with same surface board linked on both side edges, get a conclusion that surface boards restrict the bending flection of stud in weak axis direction of section by his strong side-move-resist rigid in oneself plane, consequently make the bending flection modes of stud change, and heighten the load bearing capacity of studs about 20 pencent.Futhermore this article also brings forward some advices on the ones who will do same experiments in the future.
