Load Truncation Approach for Development of Live-Load Factors for Bridge Rating

Feasibility Study on Dynamic Bridge Load Rating

Load Rating and Frp Retrofitting of Bridge Abutment Timber Piles

Calibration of Load and Resistance Factors for Reinforced Concrete

Current approach for designing of reinforced concrete members is based on the load and resistance factor. However the load and resistance parameters are random variables, the constant values have been designated for them in the designing procedure. Assuming these factors as the constants, will be led to the unsafe and uneconomical designs. Safe designing of structures requires appropriate recog...

Utilization of Handheld Field Testing System for Improvement of Bridge Load Rating Values in Pontis

Due to the growing number of structurally deficient bridges in the United States, methods for determining the structural performance of in-service bridges is vital to the preservation of the nation’s bridge network. By utilizing field testing, the response of the bridge due to a known traffic load can be assessed, and more accurate structural performance can be determined. The objective of this...

Live load model for highway bridges *

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...
