Abstract: Precast concrete sandwich panels with wire mesh are widely used in civil engineering both as structural elements and non-structural elements with the advantage of light-weight, high load-bearing and the potential for standardization. It has been accepted as cladding component in the past decades years and now it begins to serve in residential building as a reliable structural system. The available methods of strength prediction have been listed and compared to draw the conclusion that the effect of additional eccentricity on strength can be negligible if the slenderness ratio is less than 15 based on the existed experimental results. The analysis method with the assumption that one concrete layer is subjected to compression while the other layer is in tensile loading has good feasibility and can be used in structural design for this kind of wall system.

Keywords: wire mesh；concrete sandwich panel； eccentric loading；slenderness ratio
