摘要： In order to design an infrastructure of an elevated bridge, first a target ductility factor &mgr;d and target natural period Td for the infrastructure are set in connection with an assumed earthquake motion. Subsequently, a yield seismic coefficient for the target ductility factor &mgr;d and target natural period Td is obtained from a yield seismic coefficient spectrum for the assumed earthquake motion as a design seismic coefficient Kh. On the other hand, a target yield rigidity Kd corresponding to the target natural period Td is obtained. Subsequently, the design seismic coefficient Kh is used to obtain a design horizontal load bearing capacity Hd and a displacement corresponding to the design horizontal load bearing capacity Hd is obtained as a design yield displacement &dgr;d from the target yield rigidity Kd. Subsequently, the design horizontal load bearing capacity Hd is distributed into a horizontal force Hf to be borne by the RC rigid frame and a horizontal force Hb to be borne by the damper-brace. Next, member sections of the RC rigid frame and the damper-brace are set so that the RC rigid frame and the damper-brace resist the horizontal forces Hf, Hb with ultimate load bearing capacities and displacements corresponding to the horizontal forces Hf, Hb equal the product of the design yield displacement &dgr;d and target ductility factor &mgr;d, that is, &dgr;d&mgr;d.

摘要： A method for designing a seismic frame. Models of a reinforced concrete rigid frame and a seismic frame structure, respectively, are provided. Based on distances between components and damper load displacement in the seismic frame structure model, a burden (Prc) for the reinforced concrete rigid frame is calculated. A section design of the seismic frame structure is performed according to the elasto-plastic analyses.
