Abstract: For complex structures, construction sequence directly affects component’s internal force. The transmission way of inclined support’s horizontal forces in the floor is the key point in design of inclined support and truss combined transfer structure. Mechanics characteristics of the transfer floor of Guangming New District public service platform under inclined support transfer structure’s horizontal forces were studied. Comparing the calculations of two different schemes of construction process, influence of construction sequence of the transfer floor on key components’ internal forces and horizontal force’s transmission way was studied. The results show that construction process scheme has certain effect on the force distribution way in beams and slabs. This affection is more obvious when inclined support’s horizontal forces are large and the great hidden danger would appear if it’s inappropriately managed.

Keywords: inclined support and truss combined transfer structure; large-span arch-transfer structure; transfer floor; construction sequence
