Car Ramp strucutral calculations

详细信息

Hi
We are looking to have some structral calculations done for a ramp that will lead onto a 1st floor (currently a flat roof). The height is only 1.5m from the floor to the ground floor. The entrance will be from a side road. The ceiling is constructed of concrete slabs supported with RSJ's. Half of the current 1st floor is utilised as a warehouse housing considerable weights. Images can be provided. Concrete slab is 250mm thick.
We want to connect the ramp to this slab and need to know the best way to do this.
