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. ...
Experimental Analysis of Prestressed Approach Slab Behavior The temperature gradient in the approach slab adjacent to bridge was smaller than that adjacent to pavement. The patterns and magnitudes of vertical displacements were directly related to the temperature gradient at the measuring location. ... ...
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 ...
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 ...
Connection details for PBES5 Precast voided slab Approach slab panels Inverset Precast NEXT beam Spliced girders Bulb tee and Wolf girders Precast box culverts Patented bridges in steel; proprietary bridges such as US Bridge, Inverset, Acrow and Mabey types Use of aluminum and high-performance st...
Pre-cast Concrete:This is an option that can be appropriate for relatively small residential bridges for the DIY approach.It involves creating a trough to an appropriate depth, stabilizing/leveling that with landscape cloth and crushed stone and putting heavy pre-cast concrete (like cinder blocks)...
481 Accesses Metrics details Abstract Bridges will inevitably experience structural damage during long-term operation, which will decrease their structural load bearing capacity and durability. The vibration characteristics of bridge structures can be used as evaluation indicators for accurately diagnosing ...
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 ...
6.2 Research on reliability calculation approach combined with engineering application Studies or discussions on reliability calculation methods in the background of engineering applications are multitudinous in numbers, such as main factors that affect the deterioration of bridge structural performance, includin...
