Civil Engineering seismic-resistant system finite element modeling self-centering concentrically-braced frames impact This paper focuses on the finite element simulation of a self-centering concentrically-braced frame (SC-CBF) using the LS-DYNA 971 solver. SC-CBFs have been developed as a damage-free alternative to conventional concentrically braced frame (CBF) systems. Previous experimental pseudo-dynamic hybrid simulation results for SC-CBF systems indicated that the system works as intended; however, these pseudo-dynamic tests were unable to measure the effect of the mass of the SC-CBF structure on the dynamic response. This thesis analyzes the dynamic effect of the mass on a SC-CBF using the LS-DYNA software. A finite element model (FEM) of a buckling restrained braced frame (BRBF) was built to calibrate an LS-DYNA model to experimental results. This study parallels published experimental and finite element analysis results, and validates the finite element analysis method chosen to conduct the SC-CBF impact study. The objective of the thesis is to determine the effect of the mass of the SC-CBF on dynamic response. A comparative study is undertaken with two different FEMs of the SC-CBF system: one including the mass of the steel, and one treating the steel as massless. 2012-08-02 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1342448514 http://rave.ohiolink.edu/etdc/view?acc_num=akron1342448514 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
