[提要] 叉筒網(wǎng)殼是由柱面網(wǎng)殼交貫而成的新型網(wǎng)殼結(jié)構(gòu)，根據(jù)相貫線的特點可分為谷線式和脊線式兩種基本形式；膜型網(wǎng)殼是參照膜型扁殼的成型方式設計的。脊線式叉筒網(wǎng)殼在造型上最明顯的特點是光滑的圓柱面交貫形成脊線，曲面在脊線處發(fā)生突變；而膜型網(wǎng)殼曲面則是完全光滑的。為了探討脊線的造型特征對結(jié)構(gòu)性能的影響，將覆蓋平面同為正方形的單層脊線式叉筒網(wǎng)殼與膜型網(wǎng)殼進行了對比分析。
[關鍵詞] 叉筒網(wǎng)殼 膜型網(wǎng)殼 曲面造型 受力特征 對比分析Latticed intersected cylindrical shell( LICS) is a new type of latticed shell formed by intersecting of two or more cylindrical shells.Latticed membrane shell( LMS) is formed as membrane shell according to Specification for Design of Reinforced Concrete Shell Structures ( JGJ/T22-98). It is the most outstanding shape characteristic of ridge style LICS that cylinders intersect with ridge line and the surface is broken on ridge line. Contrarily, surface of LMS is thoroughly smooth. In order to reveal the shape influence to structural behavior, the comparing study between single-layer ridge style LICS and LMS which covered the same square plan is carried out.
