Then an thorough computer modeling using finite element program with material, geometry and state triple - nonlinear taken into account is carried out on a series of influencing factors, such as comparison with npn - beam splice connection, comparison of varies designed theories, and the varying of fraction coefficient, diameter, grade, pretension and arrangement of bolts, thickness of web and flanges of beam and column, splicing location, axial loading on column, etc. lots of useful conclusions are drawn form computer modelling. finally, design and construction suggestions are given out. this study fills the black in the field of steel beam - to - column connection with cantilever beam high - strength bolted - splicing at both home and abroad
然後，本文在考慮材料、幾何和狀態三重非線性的基礎上，對該連接形式進行了全面的計算機模擬，主要考慮了帶懸臂梁段全螺栓拼接的樑柱連接節點與無拼接的樑柱連接及翼緣對接焊接腹板拼接的連接節點的對比，各種設計方法之間的對比，以及翼緣拼接和腹板拼接的螺栓間距、直徑和數量，拼接點與梁端之間的距離，梁和柱的翼緣、腹板厚度，柱的軸力，接觸面的摩擦系數，翼緣和腹板拼接板的厚度等因素的影響。 -
