Abstract: If the structural members are fabricated and erected according to the structural design configuration (SDC)during the construction process of steel structures, it may lead to a considerable deviation between the structuralconstruction completed configuration and the SDC. Therefore it is necessary to take pre-set deformation values (PDV) forthe structural members during the construction process. It will be focused on three computational procedures for determiningpre-set deformation values of the structural members, namely, forward iteration method, backward iteration method andstepped comprehensive iteration method. Their advantages and disadvantages are pointed out where different constructionapproaches are employed. Numerical studies and engineering applications are given for different structural forms.
