Abstract: During an earthquake the behavior of the building is on its overall shapes, size & geometry. Now a day's many buildings are asymmetric in plan and elevation. Due to irregular distribution of mass, stiffness and strengths may cause serious damage in structural system. There are various types of irregularities in the buildings depending upon their location and scope. Mainly two types of irregularities as per IS -1893(Part-I)-2002. a) plan or horizontal irregularities b) vertical irregularities. Irregularity in structure makes analysis of the seismic behavior very complicated...........

Abstract: A conceptual proposal for retrofitting old dams such as the Old Aswan dam in Egypt is by using a shrinkage-reduced concrete mix. Cracking potential is closely related to the shrinkage rate rather than the shrinkage magnitude. In this paper three types of cement are used, Ordinary Portland cement, Sulphate Resisting cement, and Slag cement. The concrete mixes have three different cement contents with and without admixture. The results show that the increase of cement content tends to increase drying shrinkage..........

Abstract: Intense competition among construction companies urges for continuous improvement and evaluation of performance. Many researches recognized the importance of financial performance (FP) and attempted to develop a reliable model to evaluate the company FP. The main objective of this research is developing an accurate model to evaluate the financial performance of residential construction companies. Financial data of a number of residential construction companies were collected from the Egyptian Authority of Money Market in the form of balance sheets and income statement. The most six ratios affecting company financial performance were identified and calculated...............

Abstract: In this work, the variational Ritz method was formulated and applied to elastic stress analysis of rectangular plates (2a  2b) under parabolically distributed edge loads applied at the two faces x  a. The problem solved is a classical two dimensional problem of elasticity that can be solved by finding solutions of the biharmonic problem of Airy's stress function which satisfy the biharmonic problem in closed form on the plate domain and simultaneously satisfy the stress boundary conditions. Analytical solutions of this problem are difficult to obtain, hence the numerical solution...............

Abstract: A parameter used to carry out the quality control of unbound compacted soil materials is the maximum dry unit weight obtained from a standard or modified Proctor test. Being unchanged over the last decades, these tests do not fully simulate the compaction in the field. Curves of modified Proctor compaction as well as those obtained from the gyratory compactor are presented. The controlled variables in the gyratory compactor were the vertical pressure, the gyration angle, and of course the number of gyrations. The compaction curves are more or less similar disregarding the rate of gyration and gyration angle. The dynamic compaction yielded better results compared...............

Abstract: The purpose of this work is to describe the effect of fine ground dolomite on important physical and mechanical properties of concrete. Dolomite powder has some similar characteristics of cement. The replacement percentages tried were 0%, 5%, 10%, 15% and 20% by weight of cement. The compressive, split tensile and flexural strengths of concrete with dolomite powder were compared with those of the reference specimens. The results indicate that replacement of cement with dolomite powder increases the compressive, split tensile and flexural strengths of concrete.

Abstract: Ecological concern and accessibility of petroleum fuels have brought about interests in the search for substitute fuel for internal combustion engines. In conventional internal combustion (IC) engines, the compression ratio is fixed. One Basic problem is that drive units in the vehicles must successfully drive at varying speeds and loads and in different weather. If a diesel engine has a fixed compression ratio, a minimum value must be selected that can obtaina true self-ignition when starting the engine in cold start conditions. The combustion process in the internal combustion engine is changing cycle to cycle while changing load, speed,etc.............

Abstract: The study was conducted to study the effect of water-cement ratio on the compressive strength. Trial mixes were prepared using coarse aggregates only (control), at water – cement ratios of 0.4, 0.45, 0.5 and 0.55. Cubes were prepared and tested to study the compressive strength in relation to the water-cement ratio. The results indicate that the concrete having over burnt bricks as aggregates reducing the water-cement ratio from 0.55 to 0.4 increases the compressive strength from by more than 30%..
