Dam structures that span navigable waterways are inherently at a risk for seismic vibrations and as such they must be designed to resist these vibrations. These are very complex structures and subjected to various types of forces both static and dynamic in nature. However, these earthquake vibrations are fundamentally dynamic in nature and a static analysis procedure may not be adequate in designing hydraulic structures like Dam. This paper presents the dynamic time history analysis of a concrete gravity dam by using STAAD-PRO. Here Finite Element Approach is used to analyze the dam. A concrete gravity dam model is prepared in STAAD-PRO to perform the time history analysis and a comparison is done between dam with gallery (i.e openings) and dam without gallery (i.e openings).Seismic analysis is performed for both dam with gallery (i.e openings) and dam without gallery (i.e openings). Various basic loads and load combinations are used in analysis of concrete gravity dam according to IS 6512:1984 Table 1 represents basic loads and load combinations used during the analysis.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"55 1","pages":"35-39"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81132224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The governing equation of this network are internal flow in pipe equations, which consist of the continuity equation, the modified Bernoulli's equation, and the head loss due to the length of the pipe. The three equations are nonlinear algebraic equations because of the square power of the discharge in the head loss equations, which need to be solved numerically. Hard Darcy method and Newton Raphson method are used to solve the system of nonlinear equations, and to compare the solution.So, twenty four nonlinear equations (nine Bernoulli's equations and fifteen continuity equations) in twenty four unknowns discharges were got by these two method by using MATLAB code. There are not differences in the resulted discharges between Hard Darcy and Newton Raphson methods. Also, it was found that Newton Raphson was faster than Hard Darcy Method when they compared by the number of iteration. The final solution of the discharges have tested by the basic of fluid mechanics that says the summation of head losses inside a loop must be equal zero which can be seen clearly in the plots of the two methods.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"18 1","pages":"07-17"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81791254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, when used in accordance queuing system and supported by the provision of adequate support facilities it can be ascertained that the services that can be provided would be optimal. In this paper, we will report the results of research on the optimization of port facilities in the complex queuing system using fuzzy logic. We have been developing a methodology optimization of port facilities by a modeling queuing systems and simulation where the system queue complex usually consists of multiple servers connected to a particular system and has a different behavior, among which the pattern of arrival of the vessel, type of service and pattern of services provided. Calculation of seaport facilities optimization with fuzzy logic models using the arrival of the ship has a Poisson distribution of patterns while the service time has an exponential distribution pattern with unlimited resources. We found that fuzzy model is relatively faster than the existing mathematical model and fuzzy model has a high flexibility for all possible inputs are provided compared to the mathematical model.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"125 1","pages":"70-78"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79517829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In literature it is assumed that, for machine scheduling models, either there is infinite number of handling or carrier systems for the job to reach desired location or jobs are distributed on the spot from one workstation to other without travel time involved. Further it is observed that simultaneous scheduling of machines and AGVs in the FMS environments involves certain exceptional difficulties as they are treated as NP hard problems. Those difficulties are assigning AGV in sequence of task along with operation sequence of machines and operation order of machines based on precedence constraints. Trajectory based methods are powerful metaheuristic for solving combinatorial optimization problems like NP hard problems such as scheduling. In this paper, author addressed about parallel scheduling of machines and AGV’s for determining minimum makespan, mean makespan and tardiness using simulated annealing algorithm and tested over 20 standard benchmark problems collected from literature. Finally, the proposed method is compared with literature results and conclusions are depicted.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"196 1","pages":"17-22"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91431472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stabilization is being used for a variety of engineering works either in its natural form or in a processed form. Eventually all structures rest on soil foundation where the main objective is to increase the strength or stability of soil and to reduce the construction cost. Now a day the utilization of waste products with soil has gained attention due to the increasing problems of waste management. This paper presents the results of an experimental program undertaken to investigate the effect of E-waste at different dosages on black cotton soil. Different dosages of E-waste i.e. 2%, 5% and 8% were added in the soil. The performance of E-waste stabilized soil was evaluated using physical and strength performance tests namely; Atterberg’s limit, specific gravity, compaction test, unconfined compressive test, California bearing ratio (CBR) and direct shear test. Theses test were conducted in order to evaluate the improvement in the strength characteristics of the soil. From the results, unconfined compressive strength of specimen increased with an average of 2.41 kN/m 2 for fixed dosage of E-waste. After performing direct shear test, there was an improvement in angle of friction (Ф). As the percentage of E-waste increased, Ф increased. As bearing capacity is dependent on C and Ф, it was also observed that there is an increase in bearing capacity of the soil.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"9 1","pages":"76-81"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87628250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
