Steel fiber (SF) cement mortar, renowned for its dual advantages of strength and toughness, is widely used in construction, transportation, and other engineering fields. However, in actual service, it often faces challen...

The increased focus on the reduction of greenhouse gas emissions in the building and construction sector has heightened the demand for structural systems that reduce both material and embodied carbon. Pre-engineered buil...

This study investigates the superplastic deformation behavior of cold-rolled Fe–24Mn–10Al–1C (wt.%) lightweight steels without pre–heat treatment over 600–800 °C. It achieves exceptional tensile ductility, rea...

A large-diameter steel tube pile is used in a machinery factory in Shanghai to test the new produced diesel pile hammer. However, with the increase of the diesel hammer weight, it fails to meet the test requirements and ...

Soil acidity is one of the reasons for corrosion of steel piles. The material deterioration of steel pile foundation served in the acidic soil will affect the safety and durability of pile foundation. In order to underst...

Abstract CO2 curing can greatly enhance the properties of concrete while actively sequestering CO2. However, the influencing mechanisms of CO2 curing on the passivation film of steel bars in concrete remains unclear. In ...

We demonstrate how controlling the heat affected zone during laser powder bed fusion may be used to optimise the phase composition of additively manufactured (AM) components in-situ to reduce post-processing heat treatme...

Abstract In this work, the formation and evolution of the rust layer on coarse-grained (25.0 µm) and ultrafine-grained (0.5 µm) weathering steels were investigated through wet/dry cyclic corrosion test in 3.5 wt%...

Laser powder bed fusion (L-PBF) technology has undergone rapid development in recent years. Owing to its advantages of high speed, efficiency, intelligence, and full flexibility, it exhibits significant potential for rea...

Lattice structures composed by parallel members named chords (or legs for vertical configurations) and connected by diagonals are very common among steel constructions in Civil and Mechanical Engineering and in particula...

Reinforced concrete (RC) piers have been widely studied and applied in bridge construction practice. To ensure the normal operation of RC piers under corrosive environments and seismic effects, new corrosion-resistant ma...

In modern construction, steel trusses remain one of the most common types of load-bearing structures used in the construction of industrial, civil, and public buildings. Their use is driven by high load-carrying capacity...

Prestressed concrete cylinder pipe (PCCP) is composed of concrete, steel cylinder, mortar and prestressed steel wire, which has been widely used in water conveyance and diversion projects. PCCP employs high-strength conc...

Laminate composites offer an effective strategy to overcome strength-ductility trade-off by harnessing the synergistic properties of constituent metals. In the TA1/304 steel composite, a unique nano-scale heterostructure...

For the a building with 13 floors high and no basemnt located in Shanghai, short leg shear wall system is used for the superstructure, and the foundation beams with precast tubular piles are used to be the foundation typ...

It is common to use Autoclaved Aerated Concrete (AAC) blocks in the construction of partition walls and infills because of their distinctive properties, including ease of work, energy conservation, and enhanced sustainab...

Concrete-filled steel tubular (CFST) truss arch bridges are widely used in long-span bridge construction due to their high strength, good stiffness, and excellent durability. However, arch rib joints, as critical load-be...

As geography studies the social construction of space is no any longer possible to mantain a “sustantive” interpretation of space. The evolution of the social thoutht and social theory have rescued space as a subject o...

BackgroundOccupational health places often involve complex dust samples characterized by diverse compositions and a lack of prior supplementary information. These factors pose challengs in ascertaining crystal phase comp...

With the help of ABAQUS FEM software, a numerical study is carried out on the mechanical properties of bent bolted connection in shield tunnel under the effect of preload, which offers theoretical evidence for the design...

The mass use of anti-tank grenade launchers known as Panzerfausts (armoured fists) by the German Wehrmacht in the final phase of the Second World War in Europe made them an immediately formidable weapon. Faced with drama...

The settlement of subway tunnel due to the rail load after its construction has cause wide concern. But the report of dynamic characteristics of railroad considering uneven settlement has not been reported. Based on a su...

The CU triaxial tests and ring shear tests on interface between steel pipe pile and soil of a kind of intact marine soft clay with medium structure are carried out under influence of shear strain rate, and the variations...
