Purpose This study aims to further the fire resistance of prefabricated concrete beam-column joints with end-plate connection. paper analyze this joint in reinforced frame structure (PRCS). Design/methodology/approach First, accuracy model is verified by using test data. Based on this, a refined finite element PRCS two stories and spans established. The influence four working conditions different floors (positions) axial compression ratios deformation, failure are analyzed. Findings results...
In this study, a high-strength bolted prefabricated concrete beam-column junction is presented, and the joint parts are put through eight quasi-static tests. The axial compression ratio steel plate hoop thickness were used in extended parameter research using finite element software to completely examine seismic performance of construction. According findings, node's ductility coefficient ranges from 2.57 3.69, which bigger than 3. specimen loses part its bearing capacity constantly as...
A prefabricated concrete column-to-column structure connected by high-strength bolts is proposed. To explore the seismic performance and failure form of structure, finite element analysis software used to simulate low-cycle repeated load test. The hysteretic curve skeleton are obtained, stiffness degradation law, ductility energy dissipation capacity quantitatively analyzed evaluate structure. results show that coefficient basically between 2.19 4.97, most specimens greater than 3.0,...
Purpose The purpose of this study is to put forward a high-strength bolt end-plate connection prefabricated concrete beam-column joint and carry out the pseudo-static test. Design/methodology/approach ABAQUS finite element software used fire resistance performance joint. This mainly considers influence axial compression ratio, screw preload, thickness steel hoop thickness. Findings results show that has certain effect on resistance. change preload little limit. Compared with cast-in-place...
Purpose Concrete-filled steel tube structures are widely used for their high bearing capacity, good plasticity, fire resistance and optimal seismic performance. In order to give full play the advantages of concrete-filled tube, this paper proposes a prefabricated frame joint. Design/methodology/approach The column beam connected by high-strength bolted end-plate, bars in concrete welded vertically with end-plates through enlarged pier head. addition, finite element software ABAQUS is...
Abstract Starting from the research of fabricated concrete frame structure system, bolt-end plate connection applied in steel and combined is extended into reinforced to form a with high-strength connection. The quasi-static test was carried out. results show that nodes exhibit good ductility energy dissipation. In order further explore seismic performance this type structure, according experimental fitting method “fixed point pointing” law, on basis skeleton curve’ s dimensionless...
