Pier design check for bridges on F5 freeway

Piers ranging in height from twelve to seventy metres were designed for the four major bridge sites on the section of the south western freeway between Menangle and Yanderra, NSW. The piers consist of two solid tapered reinforced concrete columns each, framed in the bridge transverse direction by prestressed concrete cross beams. Piers were checked for safety at ultimate limit state by a method based primarily on the aci building code. This necessitated the calculation of column buckling loads, to modify the bending moments in the bridge longitudinal direction for pier slenderness (the p-delta effect). This paper describes a method developed to calculate the buckling loads of columns, and its use in the checking of the pier design. The method of calculating column buckling loads takes into account column self weight, continuous variation in buckling stiffness ei and various end conditions. It is programmable for desk top computers, and is therefore more suitable than matrix methods for design offices.
