The utility model belongs to a precast concrete culvert with an arc-shaped bottom and an arch-shaped top cover. The precast concrete culvert comprises an arc-shaped bottom plate (7), a left wall (1) and a right wall (6), and is characterized in that a top cover (3) is made into ...
The new $1.2 million Jackson Boulevard replacement bridge in historic Garfield Park, Chicago, Illinois, is an excellent example of the blending of architectural precast concrete with structural precast concrete. This article discusses the design considerations that led to the selection of a precast conc...
In addition, nonlinear models were calibrated with the experimental tests and then analyzed with the factored design loads to determine whether the demand, including nonlinear effects within the section, exceeded the arch section capacity. 展开 关键词: Precast concrete Culverts Load tests Arches Soil...

Resilient. Adapatable. Proven. ECO-SPAN Precast Concrete Arch Systems are the ideal choice for your next bridge project of any size or scope.
aIt was not constructed with precast segments hoisted into place but rather by pouring concrete in place into each of 26 sections, one after the other, until both legs of the arch met in the middle for a closure casting. 它未修建以到位倾吐卷扬的入地方,而是宁可被已造形的段混凝土入每一26,...
摘要: PROBLEM TO BE SOLVED: To make it possible to transfer and share load in a good state in tie site of precast concrete members forming arch-shaped construction such as a collapse prevention method of a slope, a road widening method, etc....
This paper describes the design, manufacture and construction of a buried precast, prestressed concrete arch, with a span length of 19.6 m (64.3 ft) and an overall length of 173 m (566 ft), which carries highway traffic over railway tracks near Obed in Alberta, Canada. In design, a nonl...
concrete (GPC) can be also applied in the PSCs to form a seismic resilient, environmentally sustainable while economic-effective structure type. For example, Hao et al. (2020) adopted GPC to construct the segments and BFRP as prestressed tendon, and tested them on the shake tables. It was ...
Compared to monolithic reinforced concrete (RC) buildings, precast RC buildings are more prone to the risk of progressive collapse. Therefore, there is a need for efficient methods to strengthen beam-column joints in existing precast structures for mitigating the progressive collapse. This paper studie...
