摘　　要：以振型迭加反应谱法为理论依据,用Fortran 90语言编写了三层网架的竖向地震反应分析程序。对形式新颖的斜搁四角锥三层网架进行了分析。结果表明:这种形式的三层网架杆件受力均匀,具有良好的抗震性能。Based on the mode-superpesition response spectrum method, an analysis program of space trusses was compiled with Fortran 90 computer language. With this program, a novel type of triple-layer space trusses leaning-laid pyramid triple-layer space trusses was studied. The result indicated that this novel type of triple-layer space trusses have advantages of more reasonable distribution of internal force and better capability of oppose vibrate.
