We suggest design methods regarding the evaluation of the shear strength of the eccentric beam-column joint with haunch beam and construction requirements. 1. Introduction In a reinforced concrete (RC...

... in the reinforcement for a three-dimensional slope with one row of piles. By varying pile length, pile spacing and pile location, the optimal arrangement of pile reinforcement for the slope is discussed considering both slope stability and pile mechanical behavior. Therefore, an economical as well as effective pile...

... Abstract The aim of the present study is to estimate the reinforcing effects of fiber reinforced plastic (FRP) grids embedded in polymer cement mortar (PCM) shotcrete (FRP-PCM method) on tunnel linings, under the seismic load. Direct shear test was conducted to investigate the mechanical...

... of the beam. To assess the support mechanisms of thin spray-on liners when adhered to a rock surface, the plaster beams were coated with a 5 mm thick fibreglass reinforced polymer liner. These beams were tested to study the effect the polymer liner has on restricting tensile failure of the beam. Results...

... Abstract Rock masses are often heavily jointed and instability involving falling or sliding of rock block may arise upon excavation. As such, supports or reinforcements are required to stabilize the unstable rock blocks. Accurate prediction of mode of rock block failure and volume of unstable...

... anchors, and, except the slope stability anchor, are used to reinforce structures. Generally, a dam anchor is large, and plays a very important role as a structural system supporting the safety of the dam. In this paper, we classified these as structure reinforcement anchors, and clarified their roles...

... Abstract Ground support design is usually based on previous experience and evolves over a number of years. As the rock mass conditions change with an increasing depth, the ground support performance may change and become unacceptable. That is, the installed reinforcement capacities may...

Hence proper steps should be taken to ensure the safety of the tunnel by providing suitable supports and reinforcement. Since the ground behaviour is not properly understood, it is necessary to estimate the appropriate support...
