Workplace safety is one of the most important issues in industries worldwide, and endangered by industrial accidents. Different disasters have resulted several initiatives worldwide to protect human life reduce material damage, both nationally internationally. In Bangladesh, ready-made garment (RMG) industry export-oriented business sectors, which facing challenges ensure workplace safety. The Rana Plaza collapse Bangladesh consequence such non-compliance. accident different local global...
This paper presents the steel tunnel–sand–pile interaction (TSPI) response under scaled (0.05[Formula: see text]g and 0.1[Formula: text]g) seismic excitations (Kobe Loma Prieta) sinusoidal wave (frequencies of 1, 5, 7[Formula: text]Hz) along with sand relative densities 48% 80%. For this reason, a shake table test was performed in laboratory, 3D numerical analysis by Plaxis for simulation. No joint considered length tunnel to avoid complexity. In most cases, excess pore pressure ratio...
Abstract This research presents the square root sum of squares response displacements and tunnel moments under Kobe Loma Prieta seismic excitations with a peak ground acceleration 0.05 g for various dry relative densities local sand in Bangladesh. For this reason, one‐dimensional gravitational shake table test was performed after calibration to determine performance concrete tunnel–sand–pile interaction model. A vertical 40 kg load applied on each pile cap along excitations. The experimental...
Spun precast prestressed concrete (SPC) piles have been used in many parts of the world as a viable foundation alternative. This study assessed load-carrying capacity SPC passing through deep soft subsoil layer and resting on dense sand layer. The vertical bearing an pile was estimated using various analytical methods static load tests for Jolshiri area Dhaka, Bangladesh. liquefaction potential site local seismic conditions field laboratory test data. analysis suggested that topsoil...
Abstract Tunnel–soil–pile interaction (TSPI) is a vital issue during seismic excitation because of the evaluation interactive structural behaviors tunnel. This study derives analytical formulae for proposed TSPI model under transverse horizontal shear, vertical and body waves, considering series piles along tunnel's longitudinal axis. For this reason, soil medium considered to be an isotropic, homogeneous, elastic, infinite. Also, tunnel assumed beam element connect by linear elastic...
Nakamura's method, which uses a horizontal-to-vertical Fourier spectrum ratio of microtremor, has become popular to determine the predominant period and amplification site. In this study, method is extended for earthquake ground motion recordings using new strong data recorded by JMA-87-type accelerometers. From analysis these accelerograms, ratios site different earthquakes are also found be stable irrespective magnitude, distance depth. To establish fact, attenuation relations velocity...
Abstract Slope stability is an essential aspect of geotechnical engineering. Unstable slopes or stable influenced by external factors may result in a catastrophic disaster called landslide. In seismically active areas with steep terrain, landslides commonly occur and are regarded as one the most severe threats. Bangladesh has not suffered any destructive earthquakes recent years but considerable risk facing such owing to its geological conditions. Although slope failures occurring Rangamati...
Risk-Sensitive Land-Use Planning (RSLUP) is a critical process for integrating disaster-risk management (DRM) considerations into land-use planning, which first it necessary to understand the existing risk sensitivity. This study aims develop GIS-based multi-criteria zoning approach mapping earthquake-risk sensitivity of land use at local level. The methodology comprises two main steps. Firstly, spatial evaluated based on some themes related development, use, and emergency facilities....
The proposed underground tunnel for Mass Rapid Transit Line 1, Dhaka brings immense attention to the engineers and experts not only because of its construction challenges through a densely-built city, but also potential tunneling-induced ground settlements. This very preliminary study investigates surface movement due progression boring machine (TBM) using numerical analysis. A series finite element (FE) models have been developed PLAXIS 3D, in which Mohr–Coulomb (MC), modified Cam-Clay...
