| Abstract: | The techniques for prefabrication and assembling of short box-beams based on the geometric control method are still in the beginning stage in our country.This paper emphatically describes the computation concept for the control technology for construction of short sections of pre-stressed continuous beams,including the computation of the pre-camber of the box beams and the linear computation for production and the linear computation for installation.The paper provides a computation method for reference for ... |
