The crane runway girder is an indispensable structure in industrial buildings with cranes, which is responsible for transferring the load from the crane and itself loads. The geometry properties, materials properties, and load input parameters are random variables in practice. Therefore, it must ensure the necessary reliability. This study presented the reliability assessment of the crane runway girder. To achieve the goal, the deterministic model is built based on the design approach for the crane runway girder according to EC-3. Meanwhile, the deterministic model with random input parameters has been called a stochastic model. Random variables for input design parameters are considered in the proposed procedure. The reliability assessment of the crane runway girder was based on the stochastic model and Monte Carlo simulation method. Finally, the effect of random input parameters investigated based on global Sobol sensitivity analysis was also presented.
