Simulation analysis of long-span prestressed secondary beams floor system in gymnasium under j umping loads
A stadium of primary school was taken as an example,by establishing the finite element model with ANSYS,the vertical vibration of long-span prestressed secondary beams floor system worked with different jumping frequency,number of persons and jumping numbers were analyzed.The results show that,compared with the measured values,the modified half-since-power model has a relative error of 12. 98%,which is closed to the measured values;vertical vibration acceleration caused by different people jumping synchronously increases with number of persons rising;considering the people can't jump synchronously the multiplication factor is introduced to correct the jumping loads model.
