Retaining walls are fundamental in geotechnical and structural engineering, yet their design often involves conservative assumptions that...

In modern foundation construction, pile deviation is unavoidable. Survey tolerances, drilling shifts, obstruction avoidance, and site limitations often cause pile positions to deviate from the original design layout. Traditionally, engineers must manually evaluate these deviations, revise pile reactions, check eccentricities, and redesign pile caps — a process that is time-consuming, repetitive, and highly dependent on engineering judgment.

Adisorn Owatsiriwong, D.Eng. ALPS Consultants 1. Introduction Analysis of seismic-resistant frame structures might require considering shear deformation, i.e., the use of simplified wall/pier elements in global frame analysis (Singh, 2023). Shear-deformable frame elements (Bathe 1996; Bischoff 2002) are also useful for modeling members where shear deformation is not negligible, such as deep beams, short columns, and coupling beams. Integrating the FEM with implicit time int

A built up box column supports a 16.5 m-tall signboard (Fig. 1) designed in accordance with AISC 360-16 specifications. An all-in-one MATLAB code for wind load analysis and design is developed and used to investigate the box section as shown in Fig. 2. Fig. 1 Signboard Structure Fig. 2 Box column section Based on AISC 360, this column has a slender element in compression, and a non-compact flange due to Mny. The demand/capacity ratio (DCR) can be computed from the
