A Parallel Model for Predicting the Horizontal Dynamic Behavior of Helical Wire Rope Isolators

Author(s) : GIORGIO SERINO, MARIACRISTINA SPIZZUOCO, NICOLO VAIANA
Abstract: In this paper, a one-dimensional (1d) parallel model able to simulate the horizontal dynamic behavior of Helical Wire Rope Isolators (HWRIs) in both Roll and Shear directions is proposed. The experimental tests performed on a HWRI, manufactured by Powerflex S.r.l. (Limatola, Italy), are first presen...     Read More

Feasibility of using Metakaolin as a Self-Compacted Concrete Constituent Material

Author(s) : AHMED MAHMOUD SALMAN FAISAL, HASSAN MOHAMMED HASSAN IBRAHIM, MOHAMMED ABD EL SALAM ARAB
Abstract: By minimizing the Portland cement (PC) content in concrete using supplementary cementitious material, reducing the CO2 emission to the atmosphere is occurred. Metakaolin is one of these environmentally friendly materials. One of the most promising types of concrete is Self-compacted concrete (SCC). ...     Read More

The effect of single and double curvature in optimum design of slender reinforced concrete columns

Author(s) : BARIS SAYIN, GEBRAIL BEKDAS, SINAN MELIH NIGDELI
Abstract: Slenderness is an important factor in the design of long reinforced concrete (RC) columns. It is also a major problem for RC columns which are restricted to lateral displacement. In that case, buckling is effective on the second the second order effects. The elastic curve of the columns may have sin...     Read More

In Situ Denitrification of Ground Water Using Thiosphaera Pantotropha

Author(s) : A.B.GUPTA, SUDHIR KUMAR
Abstract: A two well model was fabricated to study the application of Thiosphaera pantotropha for in situ denitrification. The effect of varying C/N (Carbon/Nitrogen) ratio (0.92-2.5) on denitrification was observed with sodium acetate as a carbon source. At C/N ratio of 2.1 the reduction in nitrate nitrogen ...     Read More
