The composite girder, which combines a steel beam with an ultra-highperformance concrete (UHPC) slab, has gained significant attention in recent years as a new type of bridge structure. However, accurately estimating the bending capacity of such girders remains a challenge, as practical methods are limited. In this article, the authors propose a theoretical approach based on the Euler-Bernoulli beam theory to determine the bending capacity of composite girders.

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.

In this paper, the continuous stiffness measurement (CSM) indentation is employed to investigate fatigue mechanical properties of structural steel under cyclic loading. For this purpose, several representative analytical approaches were introduced to estimate the basic mechanical properties including Young’s modulus and indentation hardness from the characteristics of the loading/unloading curves.

This paper aims to use the AdaBoost-DE algorithm for optimizing steel roof trusses. The AdaBoost-DE employed in this study is a hybrid algorithm in which the AdaBoost classification technique is used to enhance the performance of the Differential Evolution algorithm by skipping unnecessary fitness evaluations during the optimization process. An example of a duo-pitch steel roof truss with a span of 24 meters is carried out.

In globalization, the selection of the specifications for design practices depends on the investment agency. For example, steel truss structures can be designed using various codes, such as AISC 360-16 or EC 3. Although most specifications have recently been written in the limit state design approaches, which codes resulting in reasonable design solutions are rarely investigated.

In civil engineering, distinct mechanical properties and behaviors of structural steel rods necessitate a novel approach to material modeling. This study extends the application of recently proposed strain-hardening laws, originally developed for automotive sheet metals, to several structural steel rods (CB240-T and CB300-T). Standard uniaxial tensile tests are conducted for each examined material to obtain experimental stress strain data.

In this study, a methodology was created to evaluate the values of the yield stress of materials based on the grain boundary strengthening equation. This method was constructed by observing the average grain size and determining the mechanical properties of three microstructural phases in the weld zone (i.e. based metal, heat-affected zone, and weld metal).

This study examined the phenomenon of residual protection by suspending the operation of established ICCP systems in two wharves located in southern Victoria and monitoring the effect on the passivity of the steel via electrochemical testing. The results of the study confirm that the steel in selected elements within these structures remained passive once the ICCP system was interrupted. The primary factor in determining which elements remained passive, and the duration of passivity was the amount of charge injected into the element over the life of the ICCP system.

This work presents results from a numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was generated by a shock tube test facility designed to expose structures to blast-like loading conditions. The steel plates had an exposed area of 0.3 m × 0.3 m and experienced large deformations during the tests.
