i am analyzing a truss 33 m span 2 meters deep supporting concrete slab decking and secondry beams for the use of multipurpose sport hall (no seating) , where spacing between trusses is 4 meters, i am using DG 11 for vibration check
i would like to hear for you about the following
vibration value significantly differ if i will model my truss as supported on two hinges or support by columns 4 meters, according to DG11 there was nothing mentioned about column bending stiffness effect except for continuous members, just axial deformation is added according to the DG.
should i consider this multipurpose sport hall as aerobics activity area or sport event (my argument it is not sport event as in the DG11 sport event is in same category with lively concert)
if my truss vibration frequency f <fn but my a/g is less than 7% as per table 5.1 then truss is satisfactory for vibration limit?
thanks is advance
