Abstract:
To research the effective width of load-distribution and the calculation method for the bending capacities of UHPC(ultra-high-performance concrete)waffle one-way decks, 41 finite element models of waffle decks were established by ANSYS. Through numerical analysis, the effects of the transverse span, the size and arrangement of longitudinal and transverse ribs, the load area and the supporting conditions on the effective widths of load-distribution of the waffle one-way deck in the elastic and plastic stages were studied. The calculation formula of the effective width of load-distribution of the waffle one-way deck was fitted by considering the transverse span and the spacing of the transverse ribs. The effective distribution width method for the flexural capacity of the UHPC waffle one-way deck was proposed based on the plane section assumption. The results show that the effective width of the load distribution of the fixed waffle one-way deck is 30% to 50% less than that of the simply supported waffle one-way deck. When the transverse span L, the rib width br, the longitudinal rib spacing Sl, the transverse rib spacing St and the wheel load area a1b1 meet the requirements of a1&lt;Sl-br,b1&lt;St-br and St≤0.6L, it is suggested to calculate the effective load distribution width of waffle one-way deck by using the proposed formula. The calculation results are in good agreement with the experimental results.
