Development background of PBSD (Performance-Based Seismic Design) is stated. The advantages of PBSD are discussed and it is compared with traditional code-based design. Major issues in PBSD such as performance objectives and acceptance criteria are elaborated. Two development trends of PBSD, probabilistic performance objectives and next-generation PBSD which adopts novel performance measurements, are introduced.
The Research On Concrete Plate Thickness And Shear Connectors Spacing Of Composite Steel Plate Shear Walls
Composite steel plate shear walls consist of steel plate, reinforced concrete plate and steel frame used mechanical connectors. According to the interaction differences between steel plate and reinforced concrete plate, there are two kinds of composite steel plate shear walls: combination wall and Buckling-restrained wall. Studies were carried out to estimate the reinforced concrete plate thickness and shear connectors spacing on condition that steel plate directly handle the load with RC plate don't take part in. Discussing and making some suggestions about the formulae for determining the reinforced concrete plate thickness as well as the maximum spacing of the shear connectors in order to make suggestions for Technical specification for steel structure of Guangdong Province.
With cast-in-situ concrete hollow floor with box model more and more Widely used as an example, analyze calculation method for cast-in-situ concrete hollow floor, and simplify the method to popularize application of the structure.
This paper proves the influence of different location of the transfer floor to the fundamental dynamic characteristic, deformation characteristic and the stress change in some load bearing members and provides reference for similar projects.
