An Excel-based VBA program is developed for application of designing bridge approach slab incorporating partial elastic soil support. Additionally, a biaxial finite-difference model is developed using MATLAB for better understanding the performance of BAS in both longitudinal and transverse directions. ...
3) approach slab 搭板 1. Mechanics property and adaptability of approach slab; 桥头搭板受力特性及适应性 2. With the typical geological condition and road filling in Ningbo, the causes for bump at bridge head are analyzed and proposals recommended, using CMC jointly with the approach slab ...
Furthermore, the capacity of the approach slab (designed by using the design aids) was rated in terms of three special truck loads. For these purposes, a 3-D finite element analysis was conducted to model the interaction between the approach slab and the embankment soils. The predicted ...
DESIGN POINTS TO CONSIDER Type. The type is determined by what it’s required to carry, for example, road traffic, trains, pipelines, or water traffic, and how far the bridge needs to stretch. The materials chosen are also influenced by this. Crossing. Another significant factor is the loca...
A procedure for the limit-states design of a link slab system is also presented. Results indicate that while the crack size in the link slab exceeded the design level, the link slab fulfilled its function. Furthermore, the rotational demand from the large controlled loads as well as the ...
The type selected for a particular site depends on the width of opening to be bridged, the approach terrain, the volume of flow, the required vertical and lateral clearances, the soil and foundation characteristics, and the relative cost of alternative designs. The simplest design for small ...
The common deteriorations of slabs with a slightly curved bottom are introduced.By analyzing local finite element stress,deteriorations of slabs are considered to be caused by the lack of slab thickness and arch-rib lateral stiffness.The methods for preventing further deteriorating and the maintaining...
One approach to mitigate the response of railway bridges and ensure resilience is to install external damping devices. In this chapter, a generalized theoretical model of a bridge-viscous damper system is derived based on the rotation of the bridge deck around the neutral axis. The dampers are ...
21DT-3C wave propagation model for bridge design In this research, the 1DT-3C wave propagation approach is extended to the case of bridge design and it is proposed as a valuable solution to overcome the difficulty of taking into account the spatial variability of the seismic loading. ...
Bridge failure, which is generally associated with serious economic and life losses, is defined as the incapacity of a constructed bridge or its components to perform as specified in the design and construction requirements.
