Assessment of Site Response to Long Distance Sumatra Earthquakes
ABSTRACT – Singapore is a city state island located off the southern tip of Malaysia Peninsula. Although Singapore is located in a low seismicity area with mild winds, it is a classic example of low seismic hazard and high exposure scenario. It is about 400 km away from a highly active earthquake belt comprising the Sumatra fault and the subduction zone. The response of a building to long-dista...
متن کاملCase Studies of Damage to Tall Steel Moment-Frame Buildings in Southern California during Large San Andreas Earthquakes
On 9 January 1857, a large earthquake of magnitude 7.9 occurred on the San Andreas fault, with rupture initiating at Parkfield in central California and propagating in a southeasterly direction over a distance of more than 360 km. Such a unilateral rupture produces significant directivity toward the San Fernando and Los Angeles basins. Indeed, newspaper reports of sloshing observed in the Los A...
متن کاملSensitivity of the Earthquake Response of Tall Steel Moment Frame Buildings to Ground Motion Features
The seismic response of two tall steel moment frame buildings and their variants is explored through parametric nonlinear analysis using idealized sawtooth-like ground velocity waveforms, with a characteristic period (T ), amplitude (peak ground velocity, PGV ), and duration (number of cycles, N ). Collapse-level response is induced only by long-period, moderate to large PGV ground excitation. ...
متن کاملAerodynamic Admittance Function of Tall Buildings
The aerodynamic admittance function (AAF) has been widely invoked to relate wind pressures on building surfaces to the oncoming wind velocity. In current practice, strip and quasi-steady theories are generally employed in formulating wind effects in the along-wind direction. These theories permit the representation of the wind pressures on building surfaces in terms of the oncoming wind velocit...
متن کاملEstimating Fundamental Frequencies of Tall Buildings
Empirical estimates of the fundamental frequency of tall buildings vary inversely with their height, a dependency not exhibited by the various familiar models of beam behavior. This paper examines and explains this apparent discrepancy by analyzing the consequences of using two models to estimate such natural frequencies: A two-beam model that couples the bending of a classical cantilever to th...
