Performance of Soft-First-Story Buildings Against Earthquake Motions and Tsunami Loadings
Abstract eng: A series of earthquake and tsunami loading tests of reinforced concrete buildings with soft-first story were conducted to identify the effects of earthquake shaking preceding to the tsunami loading, which might cause the collapse of the structure. The dynamic and hydraulic tests were conducted in 2014 and the static tests in 2015 totally for five specimens out of six specimens constructed. Three specimens were tested at hydraulic testing laboratory at PARI, Kurihama, in the first series of 2014 under earthquake loading and tsunami loading. The first specimen with 50 mm square column was tested under hydraulic loading with water height of 1.0 m and survived the hydraulic loading without collapse. The second specimen with the same dimensions of 50 mm square was subjected to dynamic loading first with the maximum acceleration of 0.4 G and then the same tsunami loading of 1.0 m, in case the specimen collapsed totally under hydraulic loading. The third specimen with 75 mm square columns survived the same shaking and the tsunami loading with minor damage. In 2015, the static lateral loading were conducted to bare specimens of two types and also the survived specimen with 75 mm square columns, from which rigorous and accurate hysteretic relations under static loading could also be obtained. The effects of seismic loading on the capacity against the following tsunami wave are discussed in details with the observed behavior as well as with the calculated capacity.
