Roads and bridges lateral load distribution factor calculation problem
Abstract: In the highway bridge design, the lateral load distribution factor calculation is the core
of the design. Although roads and bridges lateral load distribution factor is calculated in different
ways, but in essence there is a difference between them. To improve the method of calculation, the
computation process more streamlined and accurate. This paper describes commonly used roads and
bridges lateral load distribution factor in the calculation and distribution of highway bridges lateral
load factor comparison, the main problem affecting the calculation of parameters analyzed.
Keyword: roads and bridges; lateral load distribution factors; calculation
