Analysis of Ceiling Slab of Office Centre

This paper is devoted to an analysis of the ceiling slab using conventional and advanced technologies, namely, lightweight panels using Cobiax bodies. The design was modeled in Scia Engineer 1.15. Lightened variant was based on the classical model slab on which it was necessary to optimize the hollow core and solid parts. To speed up the optimal distribution of the massive and lightweight panels, computer equipment was used. Acquired results were verified by manual calculation. After the overall design and assessment of the both types of slabs the results were mutually compared in order to find a preferable variant.

Prediction on the Sound Insulation of a Double -Leaf Lightweight Panels

Statistical energy analysis (SEA) is utilized to model sound transmission through a double -leaf lightweight. Calculating the sound insulation by this method and comparing with the measured data have shown that the prediction model may generate a certain difference between the prediction and experimental data, this method, moreover, might further solve the problem of the sound insulation of the complex wall structure by optimizing the configuration of the enclosure structure.
