Abstract this manuscript discusses the design parameters that potentially affect the lateral seismic response of segmental precast post-tensioned bridge piers. Means and methods analysis of a cast-in-place balanced cantilever segmental bridge: the wilson creek bridge case study by gunnar lucko thesis submitted to the faculty of. A time-history analysis is imperative in order to evaluate the effect of the prestressing initial stress levels on the dynamic response of precast segmental bridge columns and compare the performance of precast segmental bridge columns against emulative monolithic conventional bridge columns.

A thesis submitted by laxmi priya gouda (210ce2 025 ) odisha -769008, india may 2013 i a box girder is particularly well suited for use in curved bridge systems due to its high torsional rigidity high torsional rigidity enables box girders to effectively resist (f) circular c/s. The wilson creek bridge is a five-span cast-in-place concrete segmental bridge that was erected with balanced cantilever construction the bridge superstructure incorporated a camber to account for time-dependent deflections in final alignment.
Towards the end of the thesis, important design considerations that can enhance the performance of in-situ concrete stitches and robustness of precast concrete segmental bridges are presented dclanguage. This work presents a finite element method (fem) analysis of the behaviour of segmental concrete bridges, focusing on the response under combined shear and flexure, in service and ultimate limit states.
