Mechanical properties of the initial and the second parts of this curve are obtained

The 55-km-long Hong Kong–Zhuhai–Macao Bridge (HZMB) is the world’s longest sea-crossing bridge, connecting Hong Kong with Zhuhai and Macao at the mouth of the Pearl River Estuary in China, comprising 22.9-km-long steel bridges. HZMB is the leading steel bridge in China, with top-level manufacturing and installation technology. This paper outlines the steel bridge construction experiences of HZMB to

Due to the sharp change of the lateral load moment diagram in deep beams, the commonly proposed rigid connections may be incapable of proper transferring the plastic region away from the connection face into the beam. That is why prequalified connections of steel moment frames, proposed by different design codes, impose geometrical limitations on the beam span-to-depth ratio, which limits the application

For this aim, three specimens of the same dual polyurethane rubber spring are prepared to evaluate their mechanical behavior under fatigue and vibration tests. Hysteretic force–displacement

Surface preparation is a critical process in the re-painting of steel bridges wherein the grinding or blasting method has been widely used to remove coating and rust off steel surfaces. However, these methods struggle with rust removal in narrow areas, causing environmental problems such as dust scattering, and noise. In order to solve these problems, surface preparation, using a laser, has been researched

Various sensors have been installed in cable-stayed bridges to monitor the behavior of structures and external conditions. These sensors alert the administrator to take appropriate action when an abnormal signal is detected. Although inherent meaningful information about the history of structural responses in long-term accumulated measurement data are available, the methodology for utilizing such data

This paper aims to investigate the seismic performance of a composite connection system connecting CFUS beam to square CFST columns. In the joint system, the grooved cuts on the square tube allowed the U-shaped steel beam passing through

In the current regulations, there are two methods to describe the relationship between the two capacities of circular hollow section (CHS) X-joints under brace compression (Nuc) and brace tension (Nut): Nut = Nuc and Nut = fNuc (f is a coefficient larger than 1.0). In order to study the difference between Nuc and Nut of the X-joints, two experimental tests (monotonic compression load and cyclic axial

Stainless steel has superior corrosion resistance, fire resistance, and maintenance compared to carbon steel as a structural material. Although austenitic stainless steel (STS304) has mainly been used as structural steel material, lean duplex stainless steel, STS329FLD with lower nickel component (reduced to 0.5–1.0% in KS) has recently been developed as a substitute for austenitic stainless steel

The buckling and sudden capacity loss of the compression member can be prevented using a proposed tube in tube force limiting device (TTFLD). In this way, the brittle post-buckling behavior of the compression member can be converted into an elasto-plastic behavior. The TTFLD consists of two tubes with unequal diameter, one of which is placed into the other tube. The outer tube operates as a casing

As a common type of joint used in spatial grid structures, the tensile performance of bolt-sphere joints directly affects the safety of the spatial grid structure under fire.

Two CSDST columns are investigated in this paper (1) CSDST-CS with Circular outer tube and Square inner tube and (2) CSDST-CC with Circular outer tube and Circular inner tube. The confinement of concrete between the annular spaces of the inner and outer tubes is very important for their behaviour. To

Due to the rapid deterioration of reinforced concrete decks (RCD) under the combined effects of deck overloads, weather and salts, the orthotropic steel decks (OSD) that are light weight and require less construction time are being used increasingly to replace old deteriorated decks. In this paper, a numerical investigation was carried out to study the effect of reduction in superstructure weight on

Ultra-low cycle fatigue (ULCF) damage is one of the main failure modes of steel structures when subjected to intense earthquake action, such as near-field action. However, existing ULCF evaluation methods are based on the plastic strain history of structures, which requires fine numerical simulation and causes high calculation cost. In order to improve and simplify the ULCF evaluation process for steel

A series of cyclic loading tests of G20Mn5QT cast steel are carried out at the strain ratio of − 1. The results of tests show that the G20Mn5QT cast steel has the similar tendency in cyclic softening with different constant strain amplitude. A slight strain softening is observed, and then the stress states keep steady during the remaining cycles. A new damage variable is proposed considering the effects

The design of bridge is accomplished by magnifying static live load effect by a factor known as impact factor. In design codes of most of the countries, impact factor is provided as a function of bridge length or fundamental natural frequency. However, many studies recently conducted on bridge vehicle dynamics found other influencing parameters for the impact factor. In the present paper, the dynamic

The beam string structure (BSS) has been widely applied to public buildings (e.g. sports venues and exhibition centers) for its strong adaptability to architectural form and reasonable load bearing mechanism. However, most mathematical calculation methods for BSS are too complicated to be generally mastered by structural engineers, which limits the promotion and actual application. In this paper, two

The stress and strain concentration in some component has been a significant topic for structural safety assessment. However, the evaluation of the stress and strain concentration based on the widely existing solutions for linear elastic material under static loading would lead to remarkable errors when the material undergoes the dynamic loading, since the coupling effect induced by the nonlinearity

The application of optimization algorithms in structural engineering resulted in the use of this method for high-rise structures and determination

Steel frame structures are traditionally designed with bracings that stabilize the main bearing structure. Another approach is to apply the “stressed skin design” where the cladding structure takes the role of the bracings. In this research, the two approaches were analysed and compared in order to find advantages of any. A typical steel frame structure was chosen, and for the cladding, trapezoidal

The applied forces on the connector are determined using displacement

Elastomeric rubber bearings with side blocks have been extensively used as a seismic response-control device in steel girder bridges in Japan. In real scenarios, the behavior of the girder bridges with elastomeric bearings are usually complex because of the complex mechanism by which the seismically induced inertia forces at concrete deck transmits to the girder bearings. Therefore, it is important

High-height columns become more economically viable when designed with thin-walled open cross-sections. For such structural release, there is the occurrence of the flexion-torsion phenomenon and the evident loss of lateral stiffness, which can be reduced with the presence of bracing by lintels spaced at height. In the case of road bridges and overhead cranes, there is a low traffic speed, characterizing

This study aims at identifying the key parameters that affect the behavior of composite beams with shear tab connections under fire. Large axial forces are generated during a fire event due to the thermal expansion of the materials
