“…where, H (EW) and H (NS) are the Fourier amplitude spectra of horizontal in east-west and north-south directions, respectively, and V is vertical spectra value. Lachet et al (1996), Koçkar and Akgün (2012), Mase (2019), and Mase et al (2020c) highlighted that H/V Method is very useful in predicting local site condition. Spectral ratios obtained from H/V method is relatively more stable than other raw noise spectra.…”

“…Workability, low cost, and accuracy are some reasons why this method is more chosen. Several researchers, such as Gosar (2010), El-Hady et al (2012, and Mase et al (2020bMase et al ( , 2020c had performed microtremor measurements for site investigation. Generally, those previous studies emphasised on depicting site characteristic based on time-averaged shear wave velocity for first 30 m depth (V s30 ).…”

It has been known that Bengkulu City (Indonesia) is vulnerable to undergo seismic damage. This study is initiated by measuring horizontal to vertical spectral ratio (H/V) to sites in Bengkulu City using microtremor. The inversion analysis is performed to generate shear wave velocity profile. Hundreds of sites are investigated in this study. The results show that observed H/V is consistent with the theoretical H/V. National Earthquake Hazard Reduction Program code is adopted to classify the site class. The results also exhibit that Bengkulu City is dominated by Site Classes C and D. In general, this study could lead local government to consider seismic hazard mitigation for spatial plan.

“…Knowing the structure's natural vibration period will help prevent resonance in the structure [19]. Structural resonance is a state where the natural frequency in the structure is close to the imposed frequency caused by external load so that it can cause a collapse in the structure [20]. Based on SNI 03-1726-2012 and SNI 03-1726-2019 article 7.8.2, there are two limit values for the building period, namely the minimum value of the building period (Ta min ) and the maximum value of the building period ( Ta max ).…”

Aceh is one of the most earthquake-prone regions in Indonesia. It is, therefore, essential to design seismic resistance structures according to applicable standards. To reduce damage to building structures, the Indonesian government has updated the seismic-resistant design code for building and non-building structures. The seismic resistant design standard has been updated from SNI 03-1726-2012 to SNI 03-1726-2019 due to a significant change in spectrum response data. The purpose of this study was to evaluate and compare the impacts on the seismic base shear and the cross-sectional area of columns, beams, and tie beams of buildings in 23 regencies in Aceh Province based on SNI 03-1726-2012 and SNI 03-1726-2019. A typical five-story office building with medium-type soil is used in the study. For structural analysis, a particular moment-resistant frame was considered. The determination of the design response spectra is carried out by using coordinates and soil types through the website “indo spectra”. The method used is spectrum response analysis. Some different requirements in the two standards include the spectrum response curve, mass participation, and dynamic base shear. The study’s results revealed that the dynamic base shear in Sabang City had grown by 192.05 percent. Aceh Barat Daya Regency was observed to have the smallest increase in dynamic base shear, which was only 8.16 percent. The required cross-sectional area of structural columns, beams, and tie beams in Sabang City increased by 96%, 40%, and 44.44%, respectively; in the meantime, the required cross-sectional area of columns, beams, and tie beams in several regencies in Aceh province remained unchanged.

“…In this study, dredged sediments were collected from Northern Thailand where the subsurface soil is dominated by silty sand and clayey sand [37,38]. Northern Thailand is also a zone of medium to high seismic risk [39,40]. Therefore, a future investigation of the dynamic properties of the dredged sediments is recommended [41,42].…”

This paper explores the stabilisation of dredged lakebed sediments with ordinary portland cement and fly ash to repurpose the sediment as road pavement construction material. Data are obtained from previous studies on sediments collected from Phayao Lake and Huai Mae Phong Reservoir in Phayao province, and Mae Sab Reservoir in Chiang Mai province in Thailand. Empirical correlations are established between strength and stiffness parameters of the chemically stabilised dredged sediments intended for transportation and geotechnical applications. The strength and stiffness parameters considered in this study include unconfined compressive strength, the California bearing ratio, and the resilient modulus. The influence of curing period on strength development is determined. New strength and stiffness correlations are proposed and presented to describe stabilised soils based on the extensive experimental data. Optimised sediment/cement/fly ash mixtures which proved to be most effective in generating appropriated material strengths for road construction are reported.
