| description | The tubular roof prefabricated (TPR) structures consist of steel tubular roof and reinforced concrete. To make full use of tubular roof materials in the structures, the TPR structure is innovated by replacing stirrups with tie bars. This paper performed tests on two specimens with transverse reinforcement ratio as parameter to investigate the shear behavior of new TRP structure members. The results show that the number of transverse reinforcement influences the members’ failure model and shear-bearing capacity. Three-dimensional finite element (FE) models were developed to simulate the shear behavior of new TRP members, and the FE results were in good agreement with the experimental results in the tests. Based on this model, the sensitivity of different factors on the shear performance of new TRP members were analyzed. The main influencing factors were determined, and the suitability of the shear capacity calculation formulas in different codes for new TRP structure members is verified. |
