Construction stage modeling and analysis of prestressed concrete cable-stayed bridge / النمذجة و التحليل الإنشائي للكباري الملجمة سابقة الإجهاد أثناء مراحل التنفيذ Shady Kamel Esmail Elshafai ; Supervised Walid Abdellatif Attia , Eehab A.

This study deals with analysis of prestressed concrete cable-stayed bridges during and after construction implementing balanced cantilever construction method which includes the load history and geometry changes due to the construction sequence and the time-dependent effects due to creep, shrinkage and aging of the concrete under static permanent loads and investigate the effect of deck longitudinal prestressing on bridge behavior based on Aswan cable-stayed bridge as a case study in Aswan, Egypt over Nile river. A simplified procedure presented to conduct staged construction analysis based on proposed equation for iteration process after verifying the stage construction deformation calculated analysis software and how to overcome the shortcoming found. The bridge is analysis without staged construction analysis and without longitudinal prestressing to compare the result. The study shows how remarkable effect of staged construction on structural behavior and how longitudinal prestressing affect cable force distributing in staged and non-staged construction analysis
