seismic behavior of a rockfill dam with asphalt-concrete core has been studied utilizing numerical models with material parameters determined by laboratory tests. the case study selected for these analyses, is the meyjaran asphalt core dam, recently constructed in northern iran, with 60 m height and 180 m crest length. the numerical analyses have been performed using a nonlinear three dimension...

For the structural health diagnostic of concrete dams, mathematical monitoring model based on measured deformation values is great significance. The main purpose this paper to reconstruct ageing component and temperature in traditional Hydraulic-Seasonal-Time (HST) hybrid by combining values. On one hand, a better for displacement dams proposed combined with Burgers separate instantaneous elast...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

Safety control of concrete dams is required due to the potential great loss of life and property in case of dam failure. The purpose of this paper is to feed back the operational control loads for concrete dam displacement using the maximum entropy method. The proposed method is not aimed at a judgement about the safety conditions of the dam. When a strong trend-line effect is evident, the meth...

Geopolymer concrete is generally composed of alumina–silicate materials combined with alkaline solution. plays a vital role to safeguard the environment by way eliminating cement in concrete. The agricultural and industrial disposals include rice husk ash flyash can be used as binding material it activated using Concrete structures usually constitutes significant portion across nation which pie...

Abstract Common analytical assessment methods for concrete dams are unlikely to predict material fracture in the dam body because of assumption rigid behavior and uniform- or linear stress distribution along a predetermined failure surface. Hence, probabilistic non-linear finite element analysis, calibrated from scale model tests, was implemented this study investigate impact parameters (modulu...
