A test chamber was projected and built (according to ISO 16000-9 Standard) to simulate atmospheric conditions experienced by rubber infill (when applied in synthetic turf pitches) and measure accurately the airborne emissions of pollutants such as dusts and volatile organic compounds (VOC), as well as pollutants present in leachates. It should be pointed out that standard ISO 16000-9 is only co...

The use of surrogate models or metamodeling has lead to new areas of research in simulation-based design optimization. Metamodeling approaches have advantages over traditional techniques when dealing with the noisy responses and=or high computational cost characteristic of many computer simulations. This paper focuses on a particular algorithm, Efficient Global Optimization (EGO) that uses krig...

This study attempts to measure and characterize urban sprawl using its multiple dimensions in the Jamnagar city, India. The study utilized the multi-date satellite images acquired by CORONA, IRS 1D PAN & LISS-3, IRS P6 LISS-4 and Resourcesat-2 LISS-4 sensors. The extent of urban growth in the study area was mapped at 1:25,000 scale for the years 1965, 2000, 2005 and 2011. The growth of urban ar...

Infilled frame structures are commonly used in buildings. Masonry infilled RC frames are the most common type of structures used for multi-storeyed constructions in the developing countries, even in those which are located in seismically active regions also. Masonry infill walls are mainly used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. In the presen...

In order to improve the energy dissipation of the masonry infilled frame structure while decreasing the stiffening and strengthening effects of the infill panels, a new dry stacked panel (DSP) semi-interlocking masonry (SIM) infill panel has been developed. In this paper, the material properties of DSP and a traditional unreinforced masonry (URM) panel have been evaluated experimentally. A seri...

This paper presents results from an investigation of the behavior of unstiffened thin steel plate shear wall SPSW having a regular pattern of openings a.k.a. perforated SPSW . Finite element monotonic pushover analyses were conducted, first on a series of individual perforated strips with variation in perforation diameter, to develop a fundamental understanding of the behavior of complete perfo...

To guide the site staff to produce complex construction products with high quality, this paper proposes a three-dimensional digital technological process method for products. Firstly, information of is processed from perspective quality control and management. Then, geometric entities in product are modeled based on building model (BIM). expressed integrated into by model-based definition (MBD)...

Abstract The seismic behaviour studies of structures with RC frame show that the wall infill significantly improved lateral strength. However, since numerical analysis considers walls as non-structural components, rarely includes infills. It is strongly recommended in further research to investigate under load for having one important components their design process. This study developed two mo...

In the present study, friction damper, an energy dissipating passive device is explored to reduce response of open ground storey building under lateral loading due earthquake. This damper installed in selected bays so that reduced. The masonry infill wall macro-modeled form compression only diagonal members. Three different types bracing system were along with Pall – single tension brace cross ...
