Analysis of Seismic Performance of SRC-RC Transfer Columns by Different Constructional Measure
In high-rising buildings, sections of columns in bottom floors are usually big which is due to the axial-compression-ration limitation, and it is always to form short columns with poor earthquake resistance performance. As we all know, steel reinforced concrete (SRC) structure has the advantages of high bearing capacity, large Stiffness and good seismic performance. So, [...]
Experimental Study on Seismic Behavior and Nonlinear Analysis of Spatial Steel Frame Concrete L-shaped Columns
The load-bearing lightweight steel structure is built by welding the transverse and inclined lace bars on longitudinal chords, which is called the spatial steel frame. The concrete structure with spatial steel frame is gained by substituting.In order to study on the seismic behavior of spatial steel frame concrete L shaped column, including its bearing capacity, [...]
Study on the Seismic Performance of SRC-RC Transfer Column
In recent years, SRC-RC vertical hybrid structure has been used in more and more high-rise buildings at home and abroad especially in Japan. The key part of this new type of steel-concrete composite structure is the transmission story which is the lower SRC structure upward transition of the upper RC structure. The transmission story easily [...]
Shaking Table Test Study and Theoretical Analysis of High-rise Building with Truss Transfer Story
Yunian International Commercial Affairs Building is a complicated structure of high-rise building with transfer mega-truss.Combine with Shanghai Ynnian international commerce building, a model shaking table test and a ETABS finite element analysis of Shanghai Yunian international commerce building are carried out to research its seismic behavior.A 1:25 scale micro-concrete model of the building above is [...]
Anlysis of Seismic Resistance of the High-Rise EBSF Structures
Eccentric braced steel frames is refined resistant-lateral system based on concentrically braced frames,and is a kind of steel structure of high-rise building with better seismic-resistant and energy-dissipation,When an earthquake is coming,the dissipative link of an eccentrically braced frame becomes plastic earlier. then it consumes the energy of earthquake by its plastid deformantion and accordingly the [...]
Experimental Research on Seismic Behavior of Steel Tube Confined Steel Reinforced High Strength Concrete Short Columns
The aseismic performance of short column is unsatisfying, for it often has a shearing failure mode,which is typical brittle failure mode.In order to improve the seismic performance of short column, steel tube confined steel reinforced concrete column is mentioned.Steel tube confined steel reinforced concrete short column is a SRC column confined by a thin thickness [...]

Experimental Study on Seismic Performance of Mid-point in the Concrete Filled Circular Steel Tubular with Core Steel Tube
The joints of the concrete filled steel tubular(CFST) play important roles in distributing internal force and preserving globality , which is a vital position in the CFST structures. Due to the complexity of reinforced concrete(RC) and the joints of CFST, there are plenty of problems in theoretical research and engineering application.A new kind of joint [...]
