An　experiment　was　carried　out　to　investigate　mechanical　behaviour　of　laminated　tempered　glass　panel　with　two　opposite　edges　simply　supported　and　local　uniform　load　applied.　A　total　of　sixty-four　specimens　with　different　thickness　of　single　tempered　glass　layer　(T),　different　bearing　length　(BL)　and　different　length　of　loading　end　(LLE)　were　tested　at　a　slow　speed　of　monotonic　load.　The　load-deflection　curve　and　stress　distribution　in　plate　were　measured　under　local　uniform　load.　With　the　increase　of　the　length　of　loading　end,　the　failure　mode　of　the　specimens　changes,　and　the　ultimate　load　of　the　specimens　varies　greatly　with　different　failure　modes.　The　stress　distribution　of　specimens　is　basically　consistent　with　that　of　elastic　plates.　The　thickness　of　tempered　glass,　length　of　loading　end　and　bearing　length　are　all　positively　correlated　with　the　ultimate　load　of　specimens.　Among　them,　the　bearing　length　has　less　influence　on　the　ultimate　load,　but　the　thickness　of　glass　layer　has　the　most　significant　influence.　For　different　ranges　of　the　thickness　of　glass　layer,　its　influence　on　the　enhancing　effect　of　the　ultimate　load　differs　to　some　extent,　and　there　exists　the　economic　thickness　range　of　glass　layer　under　the　control　index　of　the　ultimate　load.　The　finite　element　analysis　model　of　laminated　tempered　glass　panel　under　local　uniform　load　was　established,　and　then　the　calculation　formula　of　equivalent　thickness　of　laminated　tempered　glass　panel　based　on　the　same　maximum　stress　was　proposed.　©　2021,　Editorial　Office　of　China　Civil　Engineering　Journal.　All　right　reserved.
