“…Albeit their relatively low b-values, the average for the overall regions of SSZ and SFZ was higher at 0.83 and 0.84, respectively. These values concur well with the b-values for the PSHA obtained for Sumatra Island and KL by Irsyam et al (2008) and Nabilah and Balendra (2012). Petersen et al (2004) performed PSHA for Sumatra, Singapore, and 20 Peninsular Malaysia using proposed b-value of 1.02 ± 0.16.…”

Abstract. Seismic hazard assessments -both deterministic and probabilistic, for Peninsular Malaysia have been carried out using peak ground acceleration (PGA) data recorded between 2004 and 2016 by the Malaysian Meteorological Departmentusing triaxial accelerometers placed at 19 seismic stations within the peninsula and monitored. Seismicity source modelling for the deterministic seismic hazard assessment (DSHA) used historical point sources whereas in the probabilistic (PSHA) approach, line and areal sources were used. The earthquake sources comprised the Sumatran Subduction Zone (SSZ), Sumatran 10 Fault Zone (SFZ), and local intraplate (LI) faults. Gutenberg-Richter law b-value for the various zones identified within the SSZ ranged between 0.56 and 1.06 (mean = 0.83) and that for the zones within SFZ, between 0.53 and 1.13 (mean = 0.84).Suitable ground motion prediction equations (GMPEs) for Peninsular Malaysia along with other pertinent information were used for constructing a logic tree for PSHA of the region. 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 15 50 years, respectively. Both DSHA and PSHA, despite using different source models and methodologies, conclude that the central-western cities of Peninsular Malaysia located between 2°N and 4°N are most susceptible to high PGAs due to neighbouring active Sumatran sources SFZ and SSZ. Surprisingly, the relatively less active SFZ source with low magnitude seismicity appeared as the major contributor, due to its close proximity. Potential hazard due to SSZ mega-earthquakes should not be dismissed, however. Finally, DSHA performed using the limited intraplate seismic data from the Bukit Tinggi (LI) fault 20 at a reasonable Mw 5.0 predicted a PGA of ~0.40 ms -2 at Kuala Lumpur.

“…The graphs in these figures show that the recorded PGAs in Peninsular Malaysia and Singapore were approximately close to the PGAs predicted by the other five attenuation laws (Nabilah and Balendra 2012;Zhao et al 2006;Fukushima and Tanaka 1992;Petersen et al 2004;Adnan A slight revision of the relation proposed by Fukushima and Tanaka (1990). .…”

“…More recently, the large earthquakes in Aceh in 2004 (M W 9.0) and Nias in 2005 (M W 8.6) occurred in the Sumatran subduction interface zone. Although the motions caused by these earthquakes were attenuated by distances of up to 1000 km, they still resulted in ground motions that could be felt by occupants of tall buildings built on soft soil in Kuala Lumpur and Singapore (Nabilah and Balendra 2012).…”

“…Pan and Megawati (2002) calculated the PGA values of 0.295 and 0.127 m/s 2 with the same return period for Kuala Lumpur and Singapore. In a recent seismic hazard study conducted in 2012, Nabilah and Balendra (2012) found that the PGAs in Kuala Lumpur with 10 and 2 % probabilities of exceedance over 50 years had the values of 0.165 and 0.234 m/s 2 , respectively. The main reason behind these different results is the selection of attenuation laws (Nabilah and Balendra 2012).…”

“…Since the three seismic zones have different rupture mechanisms, three sets of attenuation laws must be derived for the region. Several studies (Megawati and Pan 2010;Megawati et al 2003Megawati et al , 2005Nabilah and Balendra 2012;Petersen et al 2004) were conducted on attenuation laws for both the Sumatran fault and the Sumatran subduction earthquakes. Firstly, this paper has attempted to compare the different attenuation laws for subduction interface earthquakes of Sumatra as well as other regions with the PGAs recorded in Peninsular Malaysia and Singapore in order to classify them for the region.…”

Estimation of the maximum credible hazard in Kuala Lumpur and Singapore due to gigantic Sumatran megathrust earthquakes: based on a comparative study on attenuation laws

This paper has classified nine attenuation laws derived for subduction interface earthquakes through a comparative study based on the peak ground accelerations (PGAs) recorded in Peninsular Malaysia and Singapore. The goal of classification was to identify the attenuation laws that were the most compatible with the region. The PGAs predicted by the relations provided by Nabilah and Balendra (Earthq Eng 16:1076-1094 and Zhao et al. (Bull Seismol Soc Am 96:898-913, 2006) were found to correlate well with the recorded PGAs. The maximum credible hazard in Kuala Lumpur and Singapore was obtained by calculating the acceleration response spectra caused by three great Sumatran megathrust earthquakes (the worst possible earthquake scenarios) using Zhao et al. spectral attenuation law. Current building code in the region requires that buildings should be capable of resisting a notional ultimate lateral design load equals to 1.5 % of the characteristic dead weight, simultaneously applied at each floor (i.e., the minimum design level of buildings equals to *0.15 m/s 2 ). The results show that the risk level for structures of the two cities with natural period T n = 1-1.5 s corresponding to 10-and 15-story buildings located on hard soil sites [National Earthquake Hazards Reduction Program (NEHRP) site class C] is high as the demand spectrum due to a worst possible earthquake scenario with moment magnitude (M W ) 9.5 and an epicentral distance (R epi ) of 600 km from Singapore was noticeably higher than their design level. The results of the present study are & A. Adnan azlanadnan@utm.my A. V. Shoushtari vsabdollah3@live.utm.my M. Zare mzare@iiees.ac.ir N. S. H. Harith applicable in seismic hazard assessment projects in Peninsular Malaysia and Singapore.The most interesting conclusion from the earthquake engineering perspective, however, is that the design spectral shapes specified in IBC 2012 and Eurocode 8 (type 2) codes may not be particularly appropriate for sites that could be affected by large-magnitude, distant earthquakes.

The construction industry has become one of the major sources of global greenhouse gas (GHG) emissions. Therefore, low carbon buildings have been assigned for reduction of human impact on the environment. The aim of this research is to decrease the CO2 effect from the building sector by eventually proposing a new structure for Malaysian construction with regard to the needs of this industry. Life cycle assessment (LCA) has been performed to analyze the CO2 emission for the Malaysian residential single family house. Seven different materials or structures have been assessed and the result shows that timber prefabricated post and beam is the best choice due to releasing less CO2 emissions to the atmosphere. However, timber has become almost forgotten as building material for house builders in Malaysia in the last four decades. The alternative building scheme has been made by reinforced steel plate into wooden beam and column and timber wall (S8) to improve the building structure deficiency and load bearing while releasing less CO2 emissions in comparison to other buildings. New structure has been designed by steel plate sandwiched between wood members and held together with bolts in beam and post toward decreasing the percentage of improper design and to improve accuracy in the execution of timber structure. Thus, new scheme (S8) could be advised to house maker and government as a new policy to promote the sustainability in construction sector. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1394–1402, 2018
