Experimental and Analytical Investigation of Sandwich Panels

In order to optimize outer wall’s thickness and to reduce the required construction phases (costs) carrying walls built as “sandwich” panels (insulated wall panels) seem to be a reasonable alternative. Finished wall consists of inside insulation and two concrete wythes connected by shear connectors. It acts as composite wall up to a certain point. Load carrying ability of such elements is investigated experimentally and analytically. The experimental investigation consisted of trial loadings of model “sandwich” bords, up to the failure, under vertical, horizontal and in plane loading. The obtained results are compared with modified (based on the tests) analytical values for uniform concrete sections. Analytical values correlated well with the experimental results. Based on the results and published test results of the simmilar structures, suggestions for design of load carrying composite “sandwich” wall panels are given.
