As a kind of complex higher - order hyperstatic structure , space grid structures was ever considered as a most safe structure when it is applied widely , once a stick of member quit working , other member would help it to endure external force 空間網(wǎng)格結(jié)構(gòu)作為一種復(fù)雜的高次超靜定結(jié)構(gòu),在其廣泛應(yīng)用的同時,人們曾認為它是最為安全的結(jié)構(gòu),一旦一根桿件退出了工作,會由其它桿件幫助其承受外力。
Round steel tube members now have been widely used in space grid structures , reticulated shell structures , power transformation structures and ocean platforms , etc . most of the above - mentioned space structures are multiply hyperstatic structures under complicated stress condition 目前,圓鋼管構(gòu)件已廣泛應(yīng)用于網(wǎng)架、網(wǎng)殼、電力構(gòu)架和海洋平臺等空間結(jié)構(gòu)中。上述這些結(jié)構(gòu)大部分是高次超靜定結(jié)構(gòu),它們受力狀態(tài)比較復(fù)雜。
