Reliability Analysis For Shear In Lightweight Reinforced Concrete Bridges Using Shear Beam Database, Danile F. Jensen
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The objective of this report is to analyze and calibrate the reliability indices for shear in reinforced concrete bridge girders. Existing statistical models are based on limited experimental data from only a few research tests. These existing models show that our current procedures for analysis are about 10-15% less conservative for lightweight concrete compared to an analysis for normal weight concrete. Accurate load models are used to find shear and moment envelopes of loads applied to bridges. Analysis is based on different span lengths, span number and girder dimensions. Design calculations are performed using design values and loads calculated from …

Finite Element Modeling Of Full Depth Precast Concrete Bridge Deck Connections In Bending And Shear, Patrick H. James
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The need for reduced construction times of highway bridges has become more important recently. Precast concrete panels used for the bridge deck replacements are being used more frequently in order to achieve this reduced construction time and to also reduce the cost of the construction. Bridges can also be repaired quickly and with less cost if individual panels can be replaced when needed instead of replacing the entire bridge deck. The problem at hand is the structural integrity of these individual precast bridge deck panels. The joints in-between these panels often crack due to service stresses. These cracks expose the …
