It is easy to occur forcing deformation and appear shifting at the joint because of own change of the structure and action of other exogenic forces such as wind load and snow load in the roofing system of steel structure. As the stress is out of step, it is apt to cause cracking of binding site. It often causes water leakage at the joint of the roofing because sealing strip and silicone adhesive used at present can't move in step.
