Part of: Structures Congress XII


The poster presentation at the Structures' Congress details a retrofit analysis performed on the Gilroy Historic Commercial Building, which was instrumented during the Loma Prieta Earthquake. A three dimensional time history analysis, using the Loma Prieta Earthquake as input, was performed using the ABAQUS finite element package. The investigation of the effects of anchor spacing on the anchor forces (including dynamic punching and pulling effects) is presented, as well as the local effects of changing the anchor spacing. Such local effects include out-of-plane bending of the wall between anchors, as well as relative displacement and pounding between the diaphragm and the wall. The efficiency of shear transfer between anchors and the walls is demonstrated for various anchor spacings.
