The Deformation Analysis Of The Diaphragm Effect On The Panel Of The Lightweight Steel Construction

Along with the popularization and development of lightweight steel construction building in china, people attach great importance to the lightweight steel construction technology correspondingly. The diaphragm effect is a kind of mechanical phenomenon of lightweight steel construction. The theory of diaphragm effect is not comprehensive yet whereas there are few correlative experiments and documents at home. Therefore it's significant and essential to research into the diaphragm effect, bring forward some questions which should to be taken into account, integrate theory with practice, analyze and contrast with the phenomena of diaphragm effect.The paper introduces summarily the development of the lightweight steel construction at home and makes contrast with the definitions and the correlative specifications of diaphragm effect in domestic standards. It also introduces the definitions of diaphragm effect in overseas standards and makes a brief introduction of self-threading screw.By dint of the bulk testing data which the lightweight steel construction companies overseas have about the strength and the rigidity of diaphragm effect, the paper analyzes and contrasts the process of deformation. Applying the stabilization theory of the steel construction, it analyzes the mechanical phenomenon of diaphragm effect. Integrating with practice in projects it provides the calculation examples of the diaphragm effect and puts forward the correlative constructional demands on designing. On basis of the half-theory formulas, the paper gives analysis and explanation on the deforming of the diaphragm effect, setting forth the importance of the junction in the diaphragm effect.
