Experimental Modal Analysis of a Concrete-filled Tube Arch Bridge
This paper presents the experimental and analytical modal analysis of a concrete-filled (CFT) tube half-through arch bridge, with the span length of 90m, located at the center of Xining City, Qinghai province, China. Dynamic field test was carried out just prior to the official opening of bridge in order to inspect the dynamic characteristics of the bridge and make a baseline record for the fut...
متن کاملVertical Contraction Joint Models for Nonlinear Dynamic Analysis of Concrete Arch Dam
Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

متن کاملAgeing Effects on the Dam-Reservoir-Foundation Interaction Response of the Dez Concrete Arch Dam
In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...
متن کاملA STUDY ON NONLINEAR BEHAVIOR AND SEISMIC DAMAGE ASSESSMENT OF CONCRETE ARCH DAM-RESERVOIR-FOUNDATION SYSTEM USING ENDURANCE TIME ANALYSIS
In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...
