Galvanized Square Light Portal Frame Experiment And Design Research

Lightweight steel portal frame structure is a new building structure system wi dely used at home and abr oad, has the advant ages of li ght weight, high degree of industrialization, short construction period, high economic benefits, network layout more flexible etc.. With the rapid development of our economy, the structure of portal frame is rapidly development. This paper firstly introduces theproperties of dynamic and galvanized square of light portal frame at home and abroad, then using t h e P K P M t o t h e S E C C p o r t a l f r a m e l i g h t i n t e n s i t y, s t i f f n e s s( l a t e r a l d e f l e c t i o n l i m i t, l i m i t), i n t e g r a l s t a b i l i t y, l o c a l s t a b i l i t y, c o n n e c t i o n methods of calculation and design, design a set of construction drawings co mplete t he att ached t o the back, more to expr ess the image of the d e s i g n c o n c e p t, t h e e x p e r i me n t a l s t u d y o f l o c a l p r e s s u r e g a l v a n i z e d square pipe which is also carried on local stability,furthermore the SECC light-weight gabled frame with the total steel quantity with plant height, s p a n, c o l u m n s p a c i n g i n c e r t a i n r u l e, A n d e v e r y c o m p o n e n t o f s t e e l consumption accounts for the proportion of the composition ofeconomic galvanized square of light portal frame light steel structure buildings, which is also the doortype rigid frame and the traditional reinforced c o n c r e t e s t r u c t u r e( r o w) f o r c o m p a r i s o n, t h a t t h e c o s t o f l i g h t s t e e l structure is lower than the reinforced concrete structure, if the span of p l a n t m o r e l a r g e, i t s a d v a n t a g e i s m o r e o b v i o u s, w h i c h m a k e s t h e l i g h t- w e i gh t g a b l e d f r a me m o r e c o mp e t i t i v e i n t h e ma r k e t, a n d p u t forward reasonable suggestions galvanized square of light portal frame design of economic and galvanized square pipe of light portal fr ame standardization met hods, finally obtains the application advantage of galvanized square of light portal frame and its future what development, h o w t o c a r r y o u t t h e p r o s p e c t o f t h e d e v e l o p m e n t d i r e c t i o n o f.
