In civil engineering, the study of embankment settlement on soft ground is a vital geotechnical task in order to maintain serviceability of the road embankment, pavement, and facilities. This paper presents a study on settlements of road embankment on soft ground using vertical drains, including prefabricated-vertical drain (PVD), sand drain (SD), and sand compaction pile (SCP) on a number of packages of Hanoi – Haiphong Expressway Construction Project.

Single-storey industrial steel frames with cranes are considered as being vertically irregular in structural configuration and load distribution under strong earthquake excitations. In this paper, various frames with their spans of 20, 26, 32 and 38 m and locations built in Hanoi and Son La regions were designed to resist dead, roof live, crane and wind loads.

The current study investigates the influences of using DP on the engineering properties of the modified SCM with the HVFA based supplementary cementitious binder. Particularly, the effect of slag with higher pozzolanic reactivity partially substituting fly ash on the properties of the modified SCM was preliminarily estimated, which has not been previously explored.

This work aims to study the crack pattern in masonry-like structures by a simplified description of the medium using a variational damage model. In literature, when modeling fractures in masonry structures, capturing both fracture types, cracks in units, and cracks at the interface simultaneously, usually requires a complicated scheme.

This paper presents the free vibration and critical buckling analyses of porous plates based on the first-order shear deformation theory by the proposed three-node triangular element. The bending strain fields of the suggested element are enriched by the bubble node located at the centroid of the triangular element.

In this paper, we identify and evaluate 42 tower crane safety risk factors specific to the Vietnamese construction industry based on their probability of occurrence, severity of impact, and associated risk levels. The paper reveals that the most probable risk factor is “Unfavorable winds (including intensity, direction, etc.)” with a mean value of 3.641.

With the rapid growth of economic development, the circular economy has been raised in many international environmental and socio-economic conferences and forums nowadays. The recycling of plastic waste was one of those aspects. This paper studied the potential of directly reusing plastic bottle caps as bio-carriers in moving bed bioreactors without further waste processing.

This paper presents the experimental results of the viscosity and its influence of cement paste on both the segregation of the concrete mixture and the compressive strength of EPS-C. The research revealed that a viscosity of cement paste below 50 mPa.s results in segregation of the concrete mixture.

This study introduces a novel Ritz approximation function to analyze the free vibrations of laminated composite shallow curved beams. The methodology utilizes polynomial functions-based Fibonacci series to develop the Ritz’s approximation function. The displacement field aligns with the high-order shear deformation theory designed explicitly for shallow curved beams.
