Abstract: This paper aims to provide an optimum and reliable thermal design of a solar powered absorption cooling system in United Arab Emirates (UAE). A numerical algorithm was developed to compute the cooling capacity of the solar powered absorption system under the influence of several operating conditions, namely; hourly global radiation, flow rate, and the inlet generator temperature as well as investigating the associated environmental aspects. The proposed cooling system configuration consists basically of flat plate collectors, a stratified storage tank and an absorption chiller. A predictive model was programmed and simulated using INSEL software in order to analyse the performance of the system throughout summer season. A peak cooling demand of 20kW was estimated using Hourly Analysis Program (HAP) for a villa based in Dubai, UAE. Theobtained results showed that a minimum of about 50% of the power from the peak demand can be provided by the solar system during high levels of radiation.

Abstract: Buildings built with light weight, longer span and high slenderness may possess adequate strength and stiffness for static loads. However, increase in slenderness may create problems associated with vibration under serviceability. The structures with human rhythmic activities are sensitive to dynamic excitation. The main aim of this paper is to predict and analyze the behavior of human rhythmic activities in Steel and Composite floors (Bare steel concrete). A typical floor plan of size 16mx12m which consists of an indoor recreation centre with an arena is considered for this study. ANSYS (ANSYS 11), a computational model is usedfor this study. Usual mesh refinement technique is adopted to study the transient dynamic performance. The results indicate that the peak acceleration values when compared with limits proposed by design code IS 8002007 and ISO-2631(PART-II) are not satisfied. It is suggested that suitable stiffening or enhanced damping can be provided to counteract the rhythmic
