Seismic Risk Analysis of Concrete Gravity Dams under Near-fault ground motions Abdelhamid Hebbouche1,a, Mahmoud Bensaibi2,b and Hussein Mroueh3,c 1Ecole Nationale Supérieure d’Hydraulique, Blida-Algérie 2Departement of civil engineering, Saad dahlab university, Blida, Algeria 3Université Lille 1 Sciences et Technologies, France ahebbouche@yahoo.fr, bbensaibim@yahoo.co.uk, chussein.mroueh@polytech-lille.fr Keywords: Vulnerability curves, Earthquake, Concrete gravity dams, Uncertainties, Seismic behavior.
The following limit states are confined to structural failure modes for dams: - Material failure (LS1) – concrete (at the neck of the dam); - Sliding at the dam (LS2) – foundation interface; - Displacement at the crest of dam (LS3); - Material failure (LS4) – concrete (at the heel of the dam).
Limit stat 4 is related to material failure and it was achieved if stresses at the heel of the dam exceeds the compressive strength of the concrete (25 MPa).

A Simplified Concrete Creep and Shrinkage CEB-FIP90 Model in Long-span Bridge Design Qingxiang ZENG1,2,a, Dajian HAN2,b 1 School of Civil Engineering & Architecture, Wuyi University, Jiangmen 529020, China 2State Key Laboratory of Subtropical Building Science，South China University of Technology, Guangzhou 510640, China aqxzeng@wyu.edu.cn, bdjhan@scut.edu.cn, Keywords: Concrete Bridges, Shrinkage Strain, Creep Coefficient, Correlation Analysis.
In this paper, we considered the climate characteristics of Pearl River Delta area and the material characteristics of long-span bridge structure [5], and in terms of practical engineering, simplified the concrete shrinkage strain and creep coefficient calculation in Model CEB-FIP90 and Code JTG D62, and put forward a convenient and practical analytical calculation, thus proposed a convenient method for shrinkage and creep calculation in engineering design.
