DESIGN EXAMPLE OF A MULTIPLE COLUMN BRIDGE BENT UNDER SEISMIC LOADS USING THE ALASKA CAST-IN-PLACE STEEL SHELL Consistent with the principles of a capacity design philosophy, the ideal approach for the seismic design of reinforced concrete multiple column bridge ben... P. Silva,F Seible - 《...
Detailed design computations for the following components are included: concrete deck, prestressed concrete I-girders, elastomeric bearing, integral abutments and wing walls, multi-column bent and pile and spread footing foundations. In addition to explaining the design steps of the design example, ...
For example, Li's research group (Lepech & Li, 2009; V.C. Li et al., 2005) proposed a computational model for PVA-ECC slabs to estimate the overall moment resistance capacity against reinforcement ratio based on design guidelines (AASHTO, 2012). The model was based on the assumptions, ...
TIP wires and sensors may be damaged during installation and concrete placement. TIP measurement is a comparative method for integrity evaluation. Change in mix design may result in a huge difference when compared to the reference graph even though the concrete pile is sound....
A steel-reinforced concrete beam tested by Dotreppe and Franssen [27] is analysed in this example. Eight composite beam elements are used in the current finite element model to discretise this reinforced concrete beam. The beam, of length 6500 mm, width 200 mm, and depth 600 mm, is simply...
For example, when the normal stress is 200 kPa and the shear stress is 79 kPa and 94.8 kPa, respectively, the duration of the attenuated creep deformation about 1500 min and 2880 min. Friction resistance of interface increases, owing to free water and bound water in the soil sample are ...
For example, the friction between a base and its founding can restrain the shrinkage of the concrete in the base and cause tension. When a wall panel is cast on top of a base, the base will have already undergone some shrinkage, and it will therefore restrain the fresher concrete in the...
Steel fibres continue to have a wide range of applications in civil engineering materials. There are some structural applications where they have been used in concrete without any conventional reinforcing bars. These have been short span, elevated slabs, for example a parking garage at Heathrow Airpo...
