Simulation Of Reinforced Buckling Restrained Brace Steel Frame

Steel frame with Buckling Restrained Brace is a new kind of structure? it has a goodseismic performance, but the seismic response of it is complicated? This papersummarizes methods for calculating the earthquake response of this kind of structure,realizes the simulation on seismic response of it in MATLAB, a simulation platform isformed. The simulation provides the basis for the research of earthquake response of thiskind of structure and at the same time guids the design work of it?This paper uses resist lateral stiffness ratio to estimate the Buckling Restrained Braceof the Steel frame?There are different kinds of simulated models of this kind of structure,different kinds of analytical methods for the Buckling Restrained Brace, what's more,structure state is different under the different seismic in the same seismic fortificationtargets. Based on the above, this paper summarizes three methods for modeling andcomputing this kind of structure?The methods adopt Rayleigh damp and time-historymethod.The simulation uses MATLAB program to realize the reinforced structure of Steelframe and Buckling Restrained Brace. It establishs pre-processing module to input frameinformation and Buckling Restrained Brace information. It establishs modeling andcomputing module, Buckling Restrained Brace works as special units influencing stiffnessand damping properties of the structure as it was said in the third method, it uses lateralstiffness matrix to enhancing computing speed. After selection and coordination ofparameters of seismic waves, it input that?Aiming at frequent earthquake, it useswilson-computing method of time-history method and store calculation results. It established post-processing module to Output the result?These modules perfect theprogress and form the simulation platform?At last, this paper analysis the result of an architectural, the validity of the simulationis proved?...
