Load Carrying Capacity of Steel Arch Reinforcement Taking Into Account the Geometrical and Physical Nonlinearity
P. Janas, L. Koubová, M. Krejsa
pages 110 - 111, full text

The paper deals with the calculation of the load carrying capacity of the steel arch reinforcements of underground and mine workings respect for the resulting large displacement and physical nonlinearities. Solution is based on the application of the so-called effective bending stiffness, which is defined as a function of the normal forces and bending moment. The results of the numerical analysis are compared with the values of the load carrying capacity, which have been experimentally obtained using strain-stress test of mining reinforcement. The computational procedure was also applied to software that allows you to very effectively calculate the load carrying capacity of steel arch reinforcements.
