Steam curing can accelerate the hydration reaction rate of concrete, enhancing production efficiency prefabricated T-beams. Excessive temperature differences during steam could lead to early cracking concrete and affect durability structures. This paper conducted experiments numerical simulations study variation law early-age field T-beams aim was seek effective schemes. The time-history T-beam under coupling effect heat ambient measured. simulated by ABAQUS UMATHT subroutine. parametric on...
Recently, the diameters and construction water depths of pile foundations planned newly built sea-crossing bridges have been increasing greatly. Hydrodynamic loads are key control factors in design super-large-diameter piles. However, most previous studies focused on inline force with a small diameter, there were few cases to consider impact transverse hydrodynamic load under wave-current actions. In this study, understand such deep-water piles, prototype was one 6.3-m piles used Xihoumen...
Precast concrete T-beam steam curing can improve production efficiency, realize large-scale of T-beams, and achieve better economic benefits. We performed tests numerical simulations on a 30-meter-long full-size precast to study the economical reasonable scheme. The found that in early stages curing, temperature at mid-span section increases faster than end-span section. highest temperatures tested beams were section., core-surface difference increased then decreased, with maximum occurring...
Abstract With the increase of ship traffic flow, size and tonnage have increased significantly, while original anti-collision design many bridges built in early China has not met protection requirements, resulting risk bridge collision by ships. Ship with can only cause huge economic losses, but also result fatal accidents, leaving a hidden danger to safety bridges. In this paper, advanced concept ship, device triple is introduced, new flexible pier technology used, additional pile isolation...
ABSTRACT In this study, eight infill strategies with multiple infilling modes (line, grid, and honeycomb) were used in manufacturing 3D printing of a polylactic acid (PLA) by fused deposition modeling (FDM) process, the resulting surface topographies tensile properties reported. The results showed that grid/line/grid honeycomb/line/ honeycomb samples sandwich structures had best fracture resistance, which depended directly on degree quality interlayer. Based analysis scanning electron...
In the construction of large‐tonnage box girder, load girder transport is generally greater than operating in highway industry; therefore, it a crucial task to carry out accurate simulation and optimization on bearing girder. For this purpose, refined modeling method 40 m/1270t studied first paper, followed by detailed stress analysis considering impact coefficient vehicles most unfavorable conditions. Tracking tests dead load, prestressed have shown that calculated values obtained models...
