The use of rolled steel sections is typical in offshore topside, while recent developments are focused on coped sections to accommodate service lines and fire hydrants. Coped beams are better alternatives without compromising the load-bearing …

Steel Circular Hollow Section (CHS) joints have been extensively utilized in construction. Current research mainly focuses on joints reinforced in unloaded states, reinforcement under load less commonly addressed. This study examines the …

A lateral-torsional buckling (LTB) experimental study has been firstly investigated for an externally pre-stressed (PS) steel beam with/without un-bonded central deviator. Analytical and numerical studies related to elastic LTB of the PS beam are …

Open web steel beams are lightweight and economical flexural members designed for transverse as well as lateral loadings. Despite the fact that it is frequently utilised due to its multiple benefits, its behaviour remains unclear. This study …

The beam-to-column connections are the most vulnerable locations in steel Moment Resisting Frames (MRFs) subjected to seismic loading. The cyclic deterioration of these structural elements during the earthquakes may cause their failure under …

The purpose of this study is to analyze the ultimate strength and behavior of a triangular frame and a square frame of an electric transmission tower. An investigation of collapse mechanisms, including partial and overall buckling failures of leg …

Network arch bridges under the action of vertical loads are affected by out-of-plane instability phenomena, which strongly reduce their structural integrity. Current design codes on steel arch bridges do not provide complete and adequate …

X-type lattice truss panel structure (LTPS) with high strength-weight ratio has anisotropic mechanical properties. This paper proposes a theoretical mechanical model to give predictions of the compression, shear and bending performance of LTPS …

This paper presents the safety assessment of Eurocode 3—part 1-1 (Eurocode in EN 1993-1-1, Eurocode 3: design of steel structures—part 1-1: general rules and rules for buildings, CEN, Brussels, 2005) rules for hot-rolled members with I and H …

The steel-ultra high performance concrete (UHPC) composite deck has been increasingly concerned for the fatigue damage ameliorations on the steel bridge deck and the pavement. The UHPC plate in the composite deck featured by the favorable tensile …

The paper presents a procedure for modeling an orthotropic thin plate finite element so to have an equivalent structural response as the steel stiffened plate of same overall dimensions. New, equivalent element, homogenizes the structural …

The effective notch stress-based fatigue evaluation approach considering the effect of pavement surfacing is developed and verified in this research. Firstly, the sensitivity of stresses at fatigable welds to pavement surfacing was investigated.

In recent years, many long-span suspension bridges have been constructed and the shape finding is a key issue in the design stage. This paper presents an improved shape-finding method which can overcome the shortcomings of the previous …

This paper presents numerical works and multi-objective optimization of the energy absorbing connectors which was employed to dissipate blast/impact energy through curved plates and aluminum foam. Finite element models of the energy absorbing …

This study establishes an improved analytical method (IAM) to investigate the dynamic characteristics of composite box beam with corrugated webs (CBBCW), and the IAM has comprehensively considered the effects of several factors, such as the shear …

The investigation of the seismic integrity of petrochemical plant steel structures should be commensurable to their importance given the high necessity for human life safety and financial robustness. To date, it is demonstrated in the existing …

Vibration analysis of a thin circular cylindrical shell with closure is conducted using finite element method (FEM). Theoretically, shell vibrates in different axial modes, m; circumferential modes, n; and any of their combinations with …

The existence probability of buildings, which have been under fire and not been collapsed for various reasons is not low, thus they are in dangerous situation to deal with future earthquakes, therefore more attention due to high risk should be …

In recent decades, fiber-reinforced polymer (FRP) composites have been widely applied in strengthening structures due to their numerous advantages such as high strength and the stiffness-to-weight ratio (Shaat and Fam 2006 ; Tao et al. 2007 ; …
