There's usually an amplification factor that considers how close the piping system's natural frequencies are to the supporting structure's natural frequencies, a response modification factor to address the piping ductility, an importance factor and the elevation of the piping in the supporting structure. Spectral acceleration is a measure of ground motion that takes into account the sustained shaking energy at a particular period. Seismic hazard of Singapore and Malaysia. So just intercept the hazard curve to this value (0.00033) and get in "x" axis the PGA you are looking for. and reverse-faulting earthquakes, rock and deep firm soil deposits, earthquakes of moment magnitude M 4 to 8+, and distances up to 100 km. By gathering geologic, geodetic and seismologic data in the area, we calculated the magnitude-frequency distribution. Figure 4 shows typical vertical GRF traces from a force plate at three different speeds of 6km/h, 15km/hand sprinting. For example, 50 years lifetime with 10% of probability of exceedance yields about 500 years return period of ground motion (T=50/0.1) is the usual case, it means that the number of earthquakes per year in this case is 1/500 = 0.002. Gupta, I. We constructed regional earthquake source models and used standard published and modified attenuation equations to calculate peak ground acceleration at 2% and 10% probability of exceedance in 50 years for rock site conditions. Table 1 Expected Peak Ground Acceleration (PGA) in [m/s 2] for the different cities against annual exceedance probabilities and return periods. It is the acceration ratio of the constant acceration branch to the peak ground acceleration. PGA is an important measure for earthquake engineering and in due diligence, for example in Fannie Mae's 2014 update in their Property Needs Assessment . @article{osti_5423401, title = {Peak ground acceleration in Nevada}, author = {Anderson, J G and Depolo, C M and Bell, J W and Siddharthan, R}, abstractNote = {Quaternary faults and historical seismicity are used to estimate the deterministic and probabilistic seismic hazard of Nevada. N. Mostaghel, G. Ahmadi; Estimation of the peak horizontal ground acceleration based on peak accelerations of the components. One third to one half of peak ground acceleration is employed if an arbitrary declined value of (K h) is not utilized. in ETABS there are two approaches for spectral matching i.e. University of Engineering and Technology, Peshawar. much these parameters affect and relate to compact cities. But this value is for structures with a useful design life of 50 years only. Am i to multiply the acceleration record with (PGA'/PGA) or divide? Incremental dynamics analysis (IDA) was performed on these frames under three sets of repeated ground motion records. A three-component value can also be reached, by taking the vertical component into consideration also. The deformation of the building by the seismic combinations is compared to the ASCE-7 design to evaluate the vulnerability. The DSHA critical-worst scenario suggests PGAs of 0.07–0.80 ms−2, whilst the PSHA suggests mean PGAs of 0.06–0.42 ms−2 and 0.12–0.70 ms−2 at 10 % and 2 % probability of exceedance in 50 years, respectively. bduction zone fluctuates from 2 to 64 gal, based sustainable city compactness assessment, Levin, T.N.

We propose an equation that correlates the seismic parameters of peak ground motion acceleration (A max) and velocity (V max) commonly used to estimate damage to pipelines, building contents and non structural elements. As the identification and mapping of quartz in rocks is of great value for exploration and resource potential assessments, this study, employs thermal infrared (TIR) bands of the Advanced Space-bor. For subduction zone, nine recorded large earthquake events are analysed and regression analysis are performed to obtain a new GMPE for this region. Also, deterministic analysis doesn't provide a probability of exceedance for a given time period such as 50 or 300 years. Vertical ground acceleration is zero (k v = 0). These conclusions are also supported by comparison with 50 pairs of earthquake acceleration records. DSHA and PSHA, despite using different source models and methodologies, both conclude that the central-western cities of Peninsular Malaysia, located between 2 and 4°N, are most susceptible to high PGAs, due to neighbouring active Sumatran sources, SFZ and SSZ. However, up to now, the results of the research have been expressed and compared in terms of load-displacement capacity curves. The peak ground acceleration (PGA) is the maximum amplitude of the ground acceleration time-history. Until recently (before the occurrence, originated from the area, although the flooding of the Kenyir Dam, , Peninsular Malaysia has felt tremors from local orig, caused considerable damages to poorly built or badly.
