An optimal method to design reinforced concrete lining of pressure tunnels
The utilization of the lining type in pressure tunnels is highly dependent on the geological and hydraulic conditions. There are two types of lining, namely concrete and steel lining but steel lining is one of the most expensive arrangements. To decrease the length of steel lining in these tunnels, the concrete lining, which prevents water seepage from the surrounding rock mass, is the appropri...
متن کاملBidirectional Shaking Table Tests of a One-fourth Scale Reinforced Concrete Space Frame
Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...
متن کاملShake Table Tests of Reinforced Concrete Flat Plate Frames and Post-tensioned Flat Plate Frames
A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...
متن کاملA comparative study of two meta-heuristic algorithms in optimizing cost of reinforced concrete segmental lining
In this work, we tried to automatically optimize the cost of the concrete segmental lining used as a support system in the case study of Mashhad Urban Railway Line 2 located in NE Iran. Two meta-heuristic optimization methods including particle swarm optimization (PSO) and imperialist competitive algorithm (ICA) were presented. The penalty function was used for unfeasible solutions, and the seg...
متن کاملCracking of Concrete Cover in Frp Reinforced Concrete Elements under Thermal Loads
Synopsis: The effects of thermal loads on the structural performance of FRP reinforced concrete elements are analyzed in this paper. The difference in transverse coefficient of thermal expansion (CTE) between FRP and concrete causes the presence of tensile stresses within the concrete and, eventually, the formation of cracks when the temperature increases. As part of an inter-university experim...
