Savings and optimization in the use of steel and concrete can significantly contribute to the reduction of CO2 emission and energy consumption, promoting a greener environment for the place we live. It has been shown that the use of multi-spiral reinforcement (MSR) in square or rectangular columns can significantly save the amount of steel for transverse reinforcement and yet can still achieve a higher structural performance than conventional tie reinforcement. The paper presents a validation of a numerical model for nonlinear analysis of novel multi-spiral reinforcement in prefabricated columns. The validated model will be used for the subsequent studies and optimization of the spiral reinforcement location, diameter and pitch. Selected arrangements of the multi-spiral reinforcements have been analysed to demonstrate their effectiveness in static and cyclic response. |
