Lattice girders under cyclic loading

Fatigue of semi-precast slabs

Due to the high efficiency and flexibility of semi-precast slabs with lattice girders compared to in-situ concrete structures, the use of these slab systems increase in building and industrial construction practice. Design and construction of semi-precast slabs with lattice girders follow the national building approvals of the lattice girders. The use under fatigue loading (e.g. caused by forklift trucks in building and industrial structures or by traffic loads on bridges) is either limited or excluded and within the scope of application, lead to uneconomical results. The fatigue verification...
