Out-of-plane strength of unreinforced masonry infill panels

Simple procedures are presented for estimating out-of-plane strength of unreinforced masonry infill panels. The procedures are based on an experimental study and subsequent development of an analytical model, which are described as a preface to derivation of a simple and approximate expression for estimating out-of-plane strength of a general class of infill panels. An example is given illustrating application of the proposed guideline.
