Abstract

The advantage of adopting wall panels with lighter densities as precast wall panels (being developed in the recent past) needs to be assessed from the safety and serviceability point of view under loading. The paper presents a comparative analysis of multistoried buildings with reduced wall densities against ordinary brick walls. The type of building being considered for analysis is a G+5 RCC framed structure for residential usage. It was observed from the results that the final carpet area of the building increased when the panels were used in place of walls. With the decrease in the density of wall, no appreciable change in the volume of concrete was observed, but the savings in steel got reduced.


Description

Precast wall panels have so many advantages and applications in the construction industry. However, the advantage of adopting wall panels with lighter densities as precast wall panels (being developed in the recent past) needs to be assessed from the safety and serviceability point of view under loading. In this paper, precast wall panels having densities ranging from 800 kg/m3 to 2100 kg/m3 are considered and the building performance was observed in comparison with brick wall having density of 1900 kg/cum. The dimension of panel is considered as 8 mm thick, 60 cm wide and 3 m long. This study is expected to be useful as a basic study for improving the building performance in the aspects of economy and quality. A typical wall panel with openings for door and window is shown in Figure 1.
