Special concentrically braced frames (SCBFs) located in regions close to earthquake faults may be subjected near-fault ground motions, often characterized by pulses with long periods. These could impose additional seismic demands on structures and increase the risk for structural collapse. Currently, there is limited research collapse of SCBFs under earthquakes. This paper uses a general simula...

kuhbanan fault is in southeast margin of micro continent of iran between tabas and yazd blocks. it directed from northwest of kerman to northwest of bahabad east of bafgh (yazd). its length is about 300 km and its overall direction in iran is in southeast – northwest. this fault has caused many historical deadly earthquake and is recently more active at its southeast part near zarand city. the ...

This paper focuses on the identification of high-efficiency intensity measures to predict seismic response buildings affected by near- and far-fault ground motion records. Near-fault has received special attention, as it tends increase expected damage civil structures compared that from ruptures originating further afield. In order verify this tendency, nonlinear dynamic 3D multi-degree-of-free...

The 2016 Kumamoto earthquake (Mw 7.0) occurred in the central part of Kyushu Island, southwestern Japan, on April 16, 2016. The mainshock triggered an event of maximum acceleration 700 gal that caused severe damage to infrastructure and thousands of homes. We investigate the source location of the triggered event, and the timing of large energy release, by employing the back-projection method f...

The 1946 Aleutian earthquake was a typical tsunami earthquake which generated abnormally larger tsunami than expected from its seismic waves. Previously, Johnson and Satake (1997) estimated the fault model of this earthquake using the tsunami waveforms observed at tide gauges. However, they did not model the second pulse of the tsunami at Honolulu although that was much larger than the first pu...
