Computer Shape Finding of Form Structures

摘要: This paper presents a non-linear finite element procedure for shape finding of form structures and studies an approach wherein the engineer recognises formable curved surfaces focusing on engineer's own imagination creativity before turning to numerical analysis assist in design. With investigation simple method locating geodesic lines, convenient is presented. Another purpose this present by which compression shell shapes can be obtained inverting loads tension loading cable net system. work parallels physical models used H. Isler his thin concrete shells. The gives examples mesh generated computer visualisation several examples. It demonstrates that modelling suitable alternative process. results given show software reliable, provides designer wi...
