Timber Frame Houses with Different Insulation Materials - Seismic Analysis

摘要

The aim of this article is to present results of a dynamic numerical analysis focused on the response of two timber frame building structures exposed to seismic excitations. The first structure was insulated with mineral wool, while the second one with polyurethane foam. Specifications and technology involved in the models' construction are based on the previously conducted experimental study, upon which numerical structural models were proposed. The displacements of selected node were measured and compared between two models during the numerical investigation. The results of the study confirm that using a polyurethan foam leads to much lower displacement values comparing to the case when the mineral wood is applied as an insulation material. Thus, a positive outcome of using polyurethane foam insulation in timber frame structures exposed to seismic excitations is visible.
