Block deck using concrete More specifically, disclosed is a block deck using concrete, wherein a hollow portion is formed inside and filled with concrete so as to exhibit superior... 南景九,金东珍,孙廷一 被引量: 0发表: 2013年 RESIN CONCRETE STRUCTURE PURPOSE:To provide a structure of high ...
The optimization is performed for bridges with different span lengths and deck widths, and with various unit costs of concrete. A comparison among the PSO, CBO, and MCBO algorithms is conducted which shows the efficiency and robustness of the MCBO algorithm. 展开 ...
In that, framework to be used for a concrete framework is first formed and then a deck assembly is formed by fixing main reinforcements in a framework which will serve as a bottom plate of the deck unit for a long time, and it is transferred to the construction site and concrete is depo...
reinforced concrete (R/C) and fibre-reinforced polymer (FRP) jackets, and bearing replacement, are applied to critical members of the structure. Fragility curves are generated for the resulting retrofitted bridges using a probabilistic seismic demand model based on the results of inelastic dy...
3D solid elements (C3D8R) were used for concrete members and steel piers. The couplers and the reinforcing bars were also modeled as solid elements placed in the same positions as in the test specimen. The connection system is modeled individually as solid elements. In the case of the coupler...
Fragility Assessment for Horizontally Curved Reinforced Concrete Box Girder Bridges Using As-built DataBox girderBridgesFragility curvesHorizontally curved bridgesSeismic risk assessmentDamage to one or multiple components of a bridge could result in various conditions, extended from a cosmetically repairable ...
In this paper, three dimensional behavior of deck slab near the diaphragm of prestressed concrete (PSC) box girder railway bridge constructed by the precast span method are analyzed by using three dimensional finite element modeling and using the strut-and-tie model design of the diaphragm are ...
Xu et al. classified and located the damage of various types of reinforced concrete bridge piers subjected to earthquakes by constructing a deep learning Convolutional Neural Network (CNN) model [21]. Deng et al. utilized computer vision technology and consumer-grade cameras to process crack images...
Decks, Docks, Piers and Platforms The weather-resistant and waterproof properties of composites make them the ideal decking material for outdoor areas that will be exposed to the elements. No need to resort to cold, hard concrete or ceramics, their extruded bamboo fibre and recycled plastic com...
Bridge slab construction method and lattice bar deck-shaped precast concrete plate applied thereto Provided is a method of constructing a slab of a bridge in which a plurality of girders are placed parallel to one another on upper surfaces of neighboring piers, a plurality of cross beams are for...
