This article explores the efficacy of integrating Landsat and MODIS satellite imagery for comprehensive flood impact analysis. By employing advanced remote sensing technologies and sophisticated data processing techniques, this study offers a methodological framework that enhances the precision and depth of environmental analysis. The core methodol...

Cost overrun represents a significant challenge faced in construction projects, particularly in the realm of transportation infrastructure. The investigation into the causes of cost overruns in such projects has garnered substantial attention from both academics and the general public. Various studies conducted globally have identified diverse fact...

A defective structure has been evaluated and identified in beam models’ deflection measurement signals in much research. However, many results have not been optimally exploited and evaluated to find new parameters for data excavation. This manuscript proposes a cumulative welding model and a cumulative circle of deflection signals for a defective b...

In the construction of irrigation structures, especially the wharf structures, it is important to learn about the deformation and damage of river banks in the wharf area. From assessing the stability of the river banks, a solution can be proposed to enhance the stability of the seaports, ensuring their safety during operation. Currently, the number...

The treatment of the foundation of construction works on weak soil often raises issues that need to be resolved such as: the low load-bearing capacity of the ground, the large settlement, and stability of the large area. As a result, it is important to develop appropriate methods to treat the foundation of construction works on weak soil. Dealing w...

The article focuses on detecting structural deterioration in damaged steel beam structures by investigating changes in power spectral density (PSD) using deep learning. To simulate damage, cracks are introduced to alter the stiffness of the steel beams. The study aims to replicate a realistic traffic scenario over bridges by measuring vibration sig...

This study proposes two parameters, including the appearance frequency of harmonics (AFH) and the change in shape of the power spectral density (PSD), which are examined to assess the decline in stiffness of a bridge span. PSDs are obtained from the real vibration signals of the randomized traffic load model based on accelerometer multi-sensors tha...

Using power-spectral density (PSD) analysis for structures, we evaluated defects following a widespread research trend. During the structure’s operation, PSD not only demonstrated its structural integrity at the time of surveying but also predicted future changes in the structure. The present research used changes in PSD as a key feature for monito...

Road design must consider the factors affecting the elastic modulus of the cohesive soil used for the roadbed. Accurate determination of the elastic modulus of the pavement will help calculate properly the deformation of the pavement and prevent the appearance of cracks in the pavement; especially when the roadbed is flooded. This study is based on...
