Tuned Mass Damper (TMD) is a passive energy dissipation device which absorbs energy&amp;reduces dynamic responses. It is attached to vibratory system. The principle of Tuned Mass Damper is that, its damping ratio is same as that of main structure. The effect of TMD with optimum parameters (frequency ratio&amp;mass ration) given by Sadek, F (1997), is studied. In this paper TMD is used as soft story which is considered to be made up of RCC, constructed at the top of the building. A six storied building with rectangular shape is considered for analysis. TMDs with percentage masses 2%, 3%&amp;5.5% are considered. Three different recorded time histories of past EQ. are used for the analysis. Comparison is done between the buildings with TMD and without TMD. V.M. Thakur P.D.

H. Djuanda (Jatiluhur) Reservoir with a maximum capacity 3,000 m<sup>3</sup>/s at RWL +111.6 msl. This research was conducted to examine variation of discharge coefficient, the relationship of upstream water level and discharge, and the influence of tail water to water level at the upstream and downstream of the spillway. The method used was physical model approach of Morning Glory spillway type. The model was undistorted with 1:100 length scale. This study was conducted using discharge variation to get variation of condition at upstream and downstream of the spillway. Outputs of this research are formulation of the upstream water level and discharge, non-dimensional monogram of discharge coefficient (C), non- dimensional monogram of water level at upstream and downstream of the spillway, and ideal form of spillway crest. The result of this study can be utilized to evaluate the existing capacity condition of Morning Glory Spillway in relation to its ability to accommodate flood discharge.

Natural fabrics such as coir and jute have been used.CBR method is employed for the design of flexible pavements in most of the design offices even though it is empirical in nature, since the method is simple and convenient to apply and the CBR value of the subgrade indirectly gives the strength of subgrade soil. The results are analyzed effectively by introducing two non-dimensional factors namely, Effective Depth Ratio (EDR) and Strength Benefit Ratio (SBR). It is found that both CBR and SBR values increases with provision of composite reinforcing elements. Based on the favorable results obtained, it can be concluded that expansive soil can be successfully stabilized using composite reinforcing elements. A.V. Narasimha Rao D.

A numerical solution using Adomian decomposition method is carried out to obtain the deflection shape of the beam. A Parametric analyses of are carried out and influences of all varying parameters on the beam responses are investigated. The model includes the simultaneous effects (or couplings) of bending and shear deformations, translational and rotational inertias of all masses considered. M. Taha A. Omar M.

Solid waste management is one of the major environmental concerns. Among the waste material, plastic is the material that is the major concern to most of the environmental effects. There are different types of plastic which are classified on the basic of the physical property and how they react with the temperature. As the plastic waste is non-degradable, it must be recycled or reused. The objective of the study is to study the behaviour of the concrete which is made of the recycled plastic materials along with the study of the some of the physical properties that are related. Usually M20 grade of the concrete is the most commonly used in the constructional works, hence in this study M20 Cement concrete is considered in which the recycled plastic waste is used as the replacement of the sand in the concrete. Concrete cubes were casted taking 20% to 50 % of plastic as partial replacement of sand and tested for 7, 21, 28 days of the compressive strength. These test revealed that the optimum replacement of the recycled plastic material was 20% to 30% of the weight of the sand used in the concrete. Katakam Balakrishna Chandana Sukesh P.

Drought assessment involves analysis of spatial and temporal varying water related data. GIS is ideally suited for processing and analyzing such kind of data and to produce high quality maps. Using these capabilities, a GIS database can be created and drought severity maps can be produced. Drought assessment is being performed by different researchers using various methods. Drought severity in an area or basin is generally assessed in meteorological, hydrological and agricultural contexts. In this study, meteorological drought assessment was carried out using India Meteorological Department (IMD) method. Meteorological Drought Severity Index (MDSI) was developed based on the frequency analysis of IMD method. Vellore district, one of the drought prone district in Tamil Nadu State was selected as the study area. The methodology was applied for Samba season (major crop season) of the study area. Drought severity map was prepared in GIS environment giving blockwise meteorological drought severity status. T Murali Krishna G. Ravikumar M.

The experimental program includes testing of five concrete beams in simply supported condition with steel and GFRP bars as internal reinforcements. The experimental results were evaluated and discussed. Also the ultimate flexural capacities were calculated by theoretical calculations. A comparison made between both experimental and theoretical results. This comparison indicated that the theoretical analysis gives results which are about an average of 51.85% lower than the experimental flexural capacity for GFRPreinforced beams. The mid span average deflection of GFRP beams at 55 kN mid-point load was 4.2 times that of steel beam for same load and this can be attributed to the low modulus of elasticity of GFRP bars. G.V.

But in recent times the need to study these composite beams under dynamic and cyclic loadings is on the rise with seismic effects dominating in many places in India. Here in this study an attempt is made to assess the behaviour of composite beams under cyclic loading and later enhance the property of flexibility through fibres so that these beams have sufficient energy absorption capacity. By doing so the ductile behaviour of the concrete will also be enhanced, which is already well recognized as one of the durable properties of concrete.</p><p>In this work, results of study on 12 beams of normal concrete, concrete with steel and composite beam with steel fibre reinforcements-termed as SFRC-concrete with grades of strength M25 &amp; M30 are reported. Experimental analysis of these beams was carried out mainly to investigate the behaviour of the beams under cyclic loading and find out their energy absorption capability. Based on these tests, the cumulative ductility factor, initial stiffness and relative and cumulative energy absorption of both ordinary and SFRC beams are compared to bring out the role of fibres in steel composite beams under cyclic loadings.</p> M.
