Prediction of structural response is necessary for evaluating condition and quantifying vulnerability of structural systems exposed to seismic loads. Traditional modeling techniques for infrastructure systems such as finite elements are typically limited by inherent modeling assumptions as well as the prohibitive computational effort required for analysis. This necessitates the development of surrogate

Static and fatigue tests on two full-scale strip models subjected to four-point bending were carried out. The static nominal cracking stress of the UHPC

In shear wall building design, the initial process requires the interaction between the architectural and structural engineering groups to define the adequate wall layout, usually done with a trial-and-error procedure to fulfill architectural and engineering needs, slowing down the design process. For the engineering analysis, first, the wall thickness and length are required to check the building

The increasing demand of housing in urban areas in Latin America has driven the construction of a significant number of buildings using reinforced concrete (RC) walls with thickness equal or lower than 100 mm, with a single layer of reinforcement provided by a welded-wire mesh (WWM) or by deformed bars (DB). Several concerns related to the lack of ductility, scarce evidence on its behavior during earthquakes

Accurate fatigue life prediction facilitates the fatigue maintenance of steel bridges. Since Digital Twin can simulate the lifecycle for physical objects at various scales, this study aims to provide a Digital Twin-driven framework for non-deterministic fatigue life prediction of steel bridges. A probabilistic multiscale model was developed to depict the fatigue evolution throughout the bridge lifecycle

Flat slabs are commonly used in the construction of multi-storey buildings due to their ease of placement and installation, relatively short construction time, minimal structural floor depth and economic credentials. However, flat slabs are vulnerable to punching shear, a failure mode that typically occurs without any warning at slab-column connections. While various methods exist to improve punching

Infilling seawater sea-sand concrete (SWSSC) into stainless steel tubes may be a feasible means of overcoming the shortage of fresh water and river sand in remote coastal areas. Herein, cold-formed austenitic stainless steel (CFASS) circular tubular stub columns infilled with SWSSC were tested. The CFASS tubes had 5 different cross-sections and the concrete mixes were of strength levels 35 and 70 MPa

The plain concrete beam under three-point bending load was modelled by combining the damaged constitutive model of concrete and the Euler–Bernoulli beam theory with varied stiffness. The dynamic stiffness matrix method, in

In the dynamic analysis of simply supported railway bridges, the choice of vehicle models directly affects the quality of computed results. Simple moving load models usually overestimate the bridge response in comparison with models taking into account vehicle-bridge interaction effects. In order to compensate for this discrepancy, the Eurocode allows the increasing of structural damping for analyses

Intermediate crack (IC) debonding is a common failure mode of externally bonded (EB) FRP-strengthened RC beams. This debonding failure initiates at an intermediate crack and propagates towards a plate end. New epoxy anchor was proposed recently by the authors and has shown its effectiveness in enhancing interfacial bonding behaviour and therefore it might be effective to delay or suppress IC debonding

Fiber reinforced polymer (FRP) composite has been used effectively for the rehabilitation of concrete and steel structures in the last decades due to its excellent properties compared with conventional reinforcing materials such as steel.

In the generalized wind load method, the frames

Shell structures are material efficient structures capable of covering large spans with minimum weight. If concrete is used as the building material for the shell, it must be initially supported by a formwork. These generally rigid formworks, and their supporting falsework structure, are time and material consuming to construct. Recently, researchers have recommended the use of elastic gridshells as

In light wood-frame buildings, the gravitational and lateral force-resisting systems are composed of floor diaphragms and shear walls. During an earthquake, these walls are subjected to the simultaneous action of in-plane vertical force, shear force, and in-plane bending moment. In a mid-rise building, these internal forces can reach large magnitudes, especially on the lower stories, and could have

The temperature field and its effect are important issues related to the design and construction of bridges. For steel–concrete composite bridges, the huge difference in thermal performance between steel and concrete makes the temperature field distribution and variation more complicated.

Offshore wind turbines are subjected to cyclic loading conditions during their operational lifespan which is typically between 20 and 25 years. An important issue in fatigue design and integrity assessment of offshore wind turbine foundations is the examination of the long-term fatigue and corrosion-fatigue behaviour of steel structures in the high cycle region. High cycle fatigue tests, particularly

An equation to estimate the prestress loss in continuous unbonded prestressed concrete beams is proposed in this paper. The equation accounts for the creep and shrinkage of the concrete and the relaxation of the prestressing steel. In addition, a numerical model is developed based on the finite element method for the time-dependent analysis of these types of concrete beams. The approach also accounts

However, the collapse of the I-35 W Highway Bridge over the Mississippi river in 2007 highlighted that maintenance work could generate adverse traffic load effects (LEs), resulting in a higher probability of structural failure. This study investigated the impact of maintenance work on the lifetime traffic loading and structural safety of long-span

A beam with odd-numbered spans has distinct thermal deformation characteristics

In the design and analysis of suspension bridges, the main cables are conventionally treated as flexible ropes transmitting only tensile loads. Large-span suspension bridges used in new railways require the main cables to be designed with larger cross-sections and higher bending stiffness. The latter can affect the dynamic behavior of the entire bridge. To this end, the analytical expression of the

However, the local geometry of the weld exhibits a certain amount of variance in its topography due to dynamic effects of the welding process itself. The subsequent change in local stress concentrations affects the fatigue behaviour of welded structures. In literature, numerous equations for

Long-span cable-supported bridges are gaining considerable importance in the world. It is generally recognized that long-span cable-supported bridges can be very sensitive to wind effects due to their aerodynamic properties and deck flexibility.

This paper demonstrates the potential for significant live load-induced moments at the pinned end of a simply supported, single span, straight composite girder bridge without skewed supports. When a simple span bridge model is subjected to asymmetric vertical loading, it produces differential girder end rotation. If the pinned boundary condition is eccentric to the girder, this rotation causes varying
