The main popular theoretical method adopted to study end - plate connection is finite element technique under monotonic loading at present. this paper applies nonlinear ( material, geometry and contact ) finite element method to analyze the behaviors of connections under cyclic load at fist time. contact elements are set between end plate and column flange, screw cap and neighborhood plane, bolt bar and hole
對于端板連接的理論分析，目前國內外的研究主要局限在單向加載有限元分析范疇，本文首次採用三維非線性（包括材料、幾何與狀態非線性）有限元對端板連接進行了循環加載分析，端板與柱翼緣間、螺栓頭（帽）與相鄰板件間、螺栓桿與孔壁間都設置了反映邊界狀態的接觸單元。Based on the research of influenced parameters on constant and varying depth solid web box girder before, the shear lag aroused by the parameters including width - span ratio, outstanding flange on base slab and the position of the tendons are further studied. the investigation show that shear lag values diminish along with the decease of width - span ratio and the departure from the symmetrical axis of anchor position, but outstanding flange is contrary to the former
在前人對等截面、變截面實腹箱梁剪力滯效應影響參數研究的基礎上，本文進一步對腹板開孔的連續箱梁的寬跨比、底板翼緣伸出以及預應力錨固位置改變等參數對箱梁剪力滯的影響進行研究。Results showed that the ductility of bolt spjice is much better than welds, weaker splice joints develop larger plastic deformation, slipping between faying surfaces, bearing of bolts to hole surfaces and buckling of splicing plates are all ideal energy dissipation mechanism
試驗結果表明：螺栓拼接節點的延性遠好於樑柱焊縫連接；較弱的拼接節點產生較大的塑性變形；接觸面的滑移、螺栓與孔壁的擠壓和翼緣拼接板的屈曲都具有良好的耗能能力。It has rounded shoulders inside instead of the sharp orifice-like edge.
在內部作成圓形凸肩以代替銳緣孔板狀的側面。The edge detection approach based on cp neural network is valid to overcome the randomness of fragment dispersing and complexity of distribution of perforation holes. applying neural network approach, the influence of the negative factors is reduced in artificial detection and statistics. in this way, the target image was detected exactly and successfully
