Experiment of RC Building Frame Subjected to Bi-directional Cyclic Loading

The theories of reinforced concrete(RC) structures can divided into two distinct categories, namely “flexure governed member with axial load” and “shear or torsional member” , while the former has already had sophisticated analytical models and has been accepted by the design code, but the latter one lacks experimental support by performing a systematic study .Because of this lacking experiments, we have performed tests on a 2-story RC building subjected to bi-directional reversed cyclic loading to examine the torsional effect caused by the eccentricity at National Center for Research on Earthquake Engineering(NCREE) in Taiwan. This is an internationally-cooperated project between NCREE and the University of Houston(UH). Emphasis is placed on using simulation response histories to provide actuation forces applied to the reinforced concrete buildings subjected to reversed cyclic loading. The associated simulated response will be fed back into building characteristics for additional shake table simulations. The results will be used to correlate analytical tools and the new design methodologies.
