FORM-FINDING OF METAL GRIDSHELLS FOCUSING ON THE TRADEOFF RELATIONSHIP BETWEEN TOTAL STRAIN ENERGY FOR DEAD LOAD AND SEISMIC LOAD

A series of the proposed GRSA-based computational morphogenesis subjected to dead load and seismic load was performed for metal gridshell with square plane to investigate the effect of the level of seismic load, the period ratio between the roof and the supporting structure and the seismic-energy dissipation by the supporting structures with buckling-restrained braces on the form-found roof shape of the pareto solutions. Furthermore, the dynamic characteristic, seismic performance and buckling load were analyzed by linear static analysis, non-linear response history analysis, linear buckling analysis, non-linear buckling analysis.
