Abstract
In this study, A substractured pseudo-dynamic simulation system for low-temperature environment is developed. The developed system utilizes an open-source pseudo-dynamic system UI-SIMCOR and a sub-program which can cooperate with existent loading facility in a cold room is developed. To enhance usability of the system, another sub-program is also developed for application of general FEM software.
A simulation for a simple girder model with seismic damper is performed. Dynamic response of the damper is obtained as a part of whole structure and friction type displacement-force hysteresis curve is properly obtained. The maximum displacement is reduced 80% by energy dissipation of the damper. The result of the simulation is not affected by low temperature because the damper is stable to lowtemperature as shown in previous studies.
Hence, the system is able to work properly as a substructred pseudo-dynamic simulation facility at a low-temperature environment. For farther development, velocity control of loading equipment will improve accuracy of simulation results.
