2001 Live Load Distribution Factor Pdf In this series, dr. gregory michaelson (co director, sssba bridge technology center & associate professor, department of civil engineering at marshall university) discusses live load. This video provides an overview of vehicular live loads, structural analysis and live load distribution for bridge design.
Live Load Pdf Learn what the live load is, where and how it is used, and what values are used for the different categories. This document summarizes the live load distribution factor calculations for moment and shear in interior and exterior girders of a bridge superstructure. it verifies input parameters meet code requirements and calculates distribution factors according to aashto lrfd specifications. Multiple moving live loads over a bridge with a certain speed require a complex dynamic analysis. in practice, engineers have simplified this complex problem to an equivalent static solution to determine the forces and deflections due to live load. A live load refers to the dynamic or movable loads that a structure or component is designed to support during its use. these loads can change in magnitude and location over time.

A live load refers to the dynamic or movable loads that a structure or component is designed to support during its use. these loads can change in magnitude and location over time. Thereby, presence of deck slab leads to distribute the live load into all supporting girders because the deck slab acts as a wide plate. the girder under the wheel line is subjected to a main fraction of load while the rest of fraction is participated by the adjacent girders. 1 abstract: live load distribution is an important step in the analysis of bridge superstructures. this paper introduces a new framework to compute live load distribution for bridge girders. the model uses elastic spring elements to simulate the reaction of main girders to the deck 2 system. A live load pattern refers to the distribution or arrangement of live loads, which are temporary and variable loads on a structure, such as people, furniture, or vehicles. Bridge parameters were selected to extend the parameters and ranges of current live load distribution factors defined by aashto lrfd specifications.
