Finite Element Analysis On The Behavior Of Joint Between Steel Beam And Steel Reinforced Lightweight Aggregate Concrete Column

All is known, many merits of steel make it be widespread availability in the world. In these years, the research thermal dam focus on steel house , but the majority of research focus on the research of all-steel houses. Composite structure houses focus on free steel reinforced concrete structure. It is few for steel reinforced lightweight aggregate concrete structure in domestic and foreign. One of the subject for development organization scientific item: "The research development lightweight steel multi-layer house building system" and "A kind of late-model steel multi-layer house system's research" is discussed in this chapter.At the present time, many research organization or universities, several larger provinces in the whole country which put to a lot of tests on coal gangue lightweight aggregate concrete structural elements. But the coal gangue lightweight aggregate concrete is few used in the reality project in deed.In this case , in the second chapter of this paper the mechanical property of coal gangue lightweight aggregate concrete is analysed . In addition, if can the coal gangue lightweight aggregate concrete be used to the spraying concrete on zone of joint is discussed .Frame joint is the key part connecting beam with column. The internal forces of beams and columns transfer through joints. In this paper, an equation to calculate ultimate shear-resistant capacity of SRCLC column and steel beam joint is discussed in according to the researched achievement and technical specification for steel reinforced concrete composite structures. The mechanical behaviors of SRLC frame joints are very complex .Generally, a lot of experiments in which labor and finance are necessary to establish the influence factors on the behavior of joints must be carried out. However, these problems can be solved easily by means of finite element method for simulating the performance of the joint.The thesis mainly deals with the aspects as below:1,When an equation to calculate ultimate shear-resistants capacity of SRC column and steel beam joint is counted, the effects of flange frame are usually ignored. Only is the shear-resistant effect of steel sternum considered. ANSYS program is used to set up the joints of between steel beam and steel reinforced lightweight aggregate concrete finite element model. The joint model with ribbed stiffener and the joint model without ribbed stiffener are discussed individual.2,ANSYS program is used to analogue joints between steel beam and endocyst phon steel pipe reinforced lightweight aggregate concretes. The behavior and bearing capacity of joints are analysed. The two kind of joints on deforming,stress,stress-strain are compared, the dominance of the endocyst phon steel pipe joint is overhanged.3,ANSYS program is used to analogue the behavior and bearing capacity cyclic reverse loading of steel joint and steel lightweight aggregate concrete joint, also compare with reinforced concrete joint's circulate curve.
