An　experiment　was　carried　out　to　investigate　the　mechanical　behaviour　of　three-layer　tempered　glass　panel　on　quadrilateral　simple　bearing　against　local　uniformly　distributed　load.　Sixty-four　specimens　with　different　thickness　of　each　layer,　bearing　length　and　length　of　loading　end　were　tested　at　a　slow　speed　0.1　kN/s　of　monotonic　load.　It　was　found　that　all　specimens　failed　as　an　entire　unit,　which　was　different　from　the　failure　mode　of　ordinary　glass　or　single　layer　tempered　glass.　The　bearing　capacity　and　secant　stiffness　of　three-layer　tempered　glass　panel　increase　with　increasing　of　thickness,　bearing　length　and　length　of　loading　end.　Among　all　these　factors,　thickness　of　each　layer　showed　the　strongest　impact　on　bearing　capacity　and　secant　stiffness　of　tempered　glass　panel,　the　influence　from　bearing　length　is　negligible.　A　formula　is　proposed　to　calculate　the　bearing　capacity　of　three-layer　tempered　glass　panel　on　quadrilateral　simple　bearing　under　local　uniformly　distributed　load,　which　shows　great　rationality　and　accuracy.
