Majority of the sunken slabs are constructed with supporting beams, which leads to the uneconomy of the structure and difficult in arrangement of the centering work. In this view, it is considered to analyze a two way simply supported slab of different thicknesses with central sunk having one sunk depths.The objective of the paper is to analyze a two way simply supported slab having different thicknesses of 125,150,175,and 200mm with central sunk having depths of 250mm using Finite Element Analysis. This study significantly concludes that, adopting FE analysis using STAAD Pro for analysis of two-way sunken slab is advisable. By using FE analysis using STAAD Pro, we can avoid tedious and lengthy procedure of manual methods. From the chosen sunken slab it was observed that, there is decrease in sagging moments for sunk size of 0.25lx x 0.25ly with respect to two way slab without sunk.Analysis of Two Way Simply Supported Slabs With Central Sunk Using Finite Ele...

This paper deals with new methods to optimize design and subsequent phases, notably in SMEs specialized in manufacturing. SMEs use numerical simulation to verify that the design meets the expectations of the specification, following the current traditional process: CAD model, simulation of its behavior, changes in the CAD model... This process suffers from a number of drawbacks: no overall multi-criteria vision, use of CAD software, by nature "constructive, not considering the overall objectives (even with integration of the parameters or with considering the downstream phases). The research centre DINCCS led several projects, relying on industrial cases to consider more efficient approaches. It is proposed to reverse this process by making intensive simulations, based on trade knowledge, before design itself. In order to plan the great number of simulations, automatically designed plan of experiences are used. We discuss the application of this approach to intensive simulations. The stakes are crucial for SMEs, particularly manufacturing ones. Using numerical simulation (optimization) intensively, before setting the CAD model, they can get unexpected gains (mass, better use of the means of manufacture...). The results show that the proposed approach is a very promising new way of computer aided design..Experimental Plans and Intensive Numerical Aided Design

Plant growth depends on the use of two important natural resources, soil and water. Soil provides the mechanical and nutrient support necessary for plant growth. Water is the major input for the growth and development of all types of plants. The availability of water, its movement and its retention are governed by the properties of soil. The properties like bulk density, mechanical composition, hydraulic conductivity etc depends on the nature and formation of soil and land use characteristics in addition to the weathering processes and the geological formations. Effective management of the resources for crop production requires the need to understand relationship between soil, water and plants. Study of soil and its water holding capacity is essential for the efficient utilization of irrigation water. Hence identification of geotechnical parameters which influences the water retention capacity and the method of adding admixtures to improve the retention capacity play an important role in Irrigation Engineering. This Paper aims to focuses on improving moisture retention of soil by addition of bentonite clay and experimental analysis for monitoring the variation of moisture retention.Ground Improvement of Dune Sand Fields For The Purpose of Moisture Retention

Land cover change for the period 1987, 2002 and 2007 was investigated using satellite remote sensing data. The investigation was necessitated to determine the changes over time and how this changes influence urban flooding in Warri Metropolis Delta State, Nigeria. Landsat images of the study area for the years 1987, 2002, 2007 show that in 1987 total built-up area was 83.15km2 (16.7%) and by 2007 it was 236.76km (43.7%) this reflect an annual frequency of change of 1.09%. Marginal areas and vegetation were converted to residential areas which increased the total impervious cover of the study area and generally increased the peak runoff. The conversion of marginal areas also reduced the channel capacity thus leading to flooding. Questionnaires were also administered to get information on how the respondents perceive the cause of flood in the area, the data generated was subjected to ANOVA statistical tool using SPSS. The correlation matrix between Annual rainfall and frequency of flooding show that at P<0.01,>F crit at P < 0.05 show that uncoordinated or unregulated urbanization activities is similar in all the flood zones (Warri 1- Warr4).Impacts of Urban Land use changes on flood events in Warri, Delta State Nigeria

Masonry infill walls are commonly used in the RC frame structure buildings. Openings are inevitable part of the infill walls. Openings in infill walls significantly decrease the lateral strength and stiffness of RC frames. In the present study two-dimensional seven storeyed reinforced concrete (RC) building models are considered with of (5%, 25%, and 35% openings Bare frame and soft storey buildings are modeled considering special moment resisting frame (SMRF) for medium soil profile and zone III. Concrete block infill walls are modeled as pin-jointed single equivalent diagonal strut. Pushover analysis is carried out for both default and user defined hinge properties as per FEMA 440 guidelines using SAP2000 software. Results of default and user defined hinge properties are studied by pushover analysis. The results of ductility ratio, safety ratio, global stiffness, and hinge status at performance point are compared with the models. Authors conclude that as the percentage of openings increases, vulnerability increases in the infill walls. The user-defined hinge model is better than the default-hinge model in reflecting nonlinear behavior. The misuse of default-hinge properties may lead to unreasonable displacement capacities for existing structures. However, if the default-hinge model is preferred due to simplicity, the user should be aware of what is provided in the program and should avoid the misuse of default-hinge properties.Non-Linear Static Analysis of G+6 Storeyed RC Buildings with Openings in Infi...

This research paper describes the invention and accessibility of internet connectivity and powerful online tools has resulted a new commerce era that is e-commerce, which has completely revolutionized the conventional concept of business. E-commerce deals with selling and purchasing of goods and services through internet and computer networks. In less than a decade since the advent of the World Wide Web the technology has started to become an integral part of modern society. Possibly quicker than any other technology before it (such as the car or the telephone) the Web has begun to impinge on everyday life for a vast majority of citizens in a very short sac of time. The advent of this new technology has brought with it a whole new industry, language and potential new ways in which society, government and business will and are beginning to operate. Our findings show that, in development and diffusion of ecommerce in China, cultural issues such as “socializing effect of commerce”, “transactional and institutional trust”, and “attitudes toward debt” play a very major role. In this paper, we present and discuss these findings, and identify changes that will be required for broader acceptance and diffusion of e-commerce in China and propose approaches that businesses can use to enhance this development.E-Commerce Application Distributed Operating System
