[提要]  采用有限單元法對(duì)異形樓板進(jìn)行了數(shù)值分析，提出了一種有限單元網(wǎng)格自動(dòng)劃分的方法。實(shí)例證明了這一方法的有效性。為實(shí)現(xiàn)自動(dòng)配筋構(gòu)造設(shè)計(jì)，又提出了分段查找的動(dòng)態(tài)生成選筋方法，實(shí)現(xiàn)了鋼筋混凝土異形樓板施工圖的自動(dòng)生成。

Finite element method is adopted to analyse irregular slab. A finite element auto-meshing method is put forward which is proved highly effective. Also a dynamic generation method to select reinforcement through examing segment by segment is proposed in order to realize reinforcement auto-detzuling. As a result, auto-formin working-drawing of reinforcement concrete irregular slab is completed.
