The main purpose of this system is to enhance the seismic resistance of framed structures with masonry panels. In this system, SIM panels dissipate energy through the sliding friction between rows of SIM units during earthquake excitation. This paper aimed to find the applicability of artificial neural network (ANN) to predict the displacement behaviour of the SIM panel under out-ofplane loading. The general concept of ANN needs to be trained by related force-displacement data of SIM panel. The overall data to train and test the network are 70 increments of force-displacement from three tests, which comprise of none input nodes. The input data contain height and length of panels, height, length and width of the brick and friction and geometry angle of brick along the compressive strength of the brick with the lateral load applied to the panel. The aim of designed network is prediction displacement of the SIM panel by Multi-Layer Perceptron (MLP). The mean square error (MSE) of network was 0.00042 and the coefficient of determination (R2) values showed the 0.91. The result revealed that the ANN has significant agreement to predict the SIM panel behaviour.

Journal of Civil and Environmental Engineering, May 2, 2015

Geotechnical Engineering considerations play an important role in the design and construction of foundations of new dams. Much investigation is required to assess and evaluate the existing dams. The application of roller compacting concrete (RCC) has been accepted as a new method for constructing new dams or rehabilitating old ones. In the past 40 years there have been so many changes in the usage of RCC and now it is one of most satisfactory solutions of water and hydropower resource throughout the world. The considerations of rehabilitation and construction of dams might differ due to upstream reservoir and its influence on penetrating and dewatering of downstream, operations requirements and plant layout. One of the advantages of RCC is its rapid placement which allows the dam to be operated quickly. Unlike ordinary concrete it is a drier mix, and stiffs enough for compacting by vibratory rollers. This paper evaluates some different aspects of RCC and focuses on its preparation progress.

The mechanical aspect of FRSCC has been investigated to provide the constitutive models of shear and flexure capacity, tensile or compressive zone data. The characteristics of FRC are determined by post-cracking behavior and FRSCC is controlled by SCC workability. By using FRSCC the costs and construction period reduce significantly and its ability to place irregular section in terms of congestion of stirrups and bars and thin section is another great aspect. Consequently of this capability is to arrest cracks, fibers mixtures increased tensile strength, both at ultimate and at first crack, especially under flexural loading. The other ability of fibers are to hold matrix after extensive cracking. The transition failure from brittle to ductile by fibers is another ability of fibers which can absorb energy and survive under impact loading. In this study, investigate the fibers influence by two techniques, direct and inverse technique.

Therefore, the aggregates which are selected for the pavements are affected by higher flexural strength. Roller Compacting Concrete Pavement (RCCP) is not a new construction method. The other characteristic of this method is no bleeding and less shrinkage due to the lower amount of water. For this purpose, a roller is needed for placing and compacting. The surface of RCCP is not smooth; therefore, the most common use of this pavement is in an industrial zone with slower traffic speed which requires durable and tough pavement. For preparing a smoother surface, it can be achieved by asphalt paver. RCCP decrease the finishing cost because there are no bars, formwork, and the lesser labor need for placing the concrete. In this paper, different aspect of RCCP such as mix design, flexural, compressive strength and focus on the different part of RCCP on detail have been investigated.

After passing these years, it's become one of the popular methods in designing dams and called Roller Compacted Concrete. No slump is the specific property of the concrete of RCC dams. This type of dam needs place concrete in thin layers and compacted by roller to meet the require compaction. By one side, RCC dams can dissipate energy by stair step slope more than 70 percent of water energy and from the other side, all of the ordinary dams need to have an emergency spillway, but due to using all the length of the crest for spillway in the RCC dams, it is removed and the cost of constructing decreased. One of the most common problems which occur in the RCC dams at the beginning of its usage is hairline cracks throughout dam. This kind of cracks can start from upstream to the downstream. Rehabilitations have got several options depends on the kind of cracks and situation of cracks on dams such as drill holes, injecting grout, using different type of membrane and geomembrane, covered sealing system and covered geomembrane content. In this paper, try to investigate the different rehabilitation way of RCC in detailed and specified the best way for each kind of cracks.

Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were tested under cyclic loading within elastic region of the sample for three cycles of loading with a maximum load of 195kN for strain sensing test. During cyclic loading, fractional change in resistance (FCR) is calculated and co-relation with the stress is plotted. During strain sensing test, gauge factors (GF) were also calculated during loading and unloading on the samples. From obtained results, it is found that the concrete sample containing 1.5% of carbon fibers by weight of cement gives best co-relation between stress and FCR that can be further used for health monitoring purpose. Along with strain sensing property, damage sensing property and ultimate load carrying capacities of all the specimens are also reported in present paper with detailed explanation.
