Abstract:

Abastracts: Steel headframes are widely used in vertical lifting in large and medium-sized coal mines due to the excellent structural performance. The paper ,which bases on an actual project, expounds the key points such as model selection, force analysis, load combinations of four columns steel headframe design. Partial factors in different standards are used to calculate in the same model, and the different results are compared. The results indicate that design following the new standard is safer ,it can be used as a reference in similar projects. Meanwhile, the paper proposes the importance of preliminary plan and ideas of parameterized and modular design.
