Staggered Two-Bolt Connections in Transmission Towers: A Comprehensive Study on Failure Mechanisms and Design Codes

Buildings, Journal Year: 2025, Volume and Issue: 15(4), P. 629 - 629

Published: Feb. 18, 2025

Steel-lattice transmission towers require efficient and reliable connection designs to ensure structural safety cost-effectiveness. While traditional gusset plate connections increase their complexity weight, direct bolted offer a simpler lighter alternative. However, the adoption of staggered bolt arrangements, necessitated by geometric constraints chord angle members, challenges applicability existing design standards—particularly regarding block shear net section failure modes. This study explores behavior two-bolt through combination experimental testing numerical modeling. Twelve full-scale specimens were subjected axial tension investigate effects key parameters, including end distance, edge stagger. Finite element analyses, which incorporate material nonlinearity fracture criteria, delve deeper into stress distribution mechanisms. The results demonstrate significant deviations in modes compared with conventional parallel underscoring limitations current standards (DL/T 5486, ASCE 10-15, EN 1993-1-8) accurately predicting capacity connections. Based on identified connections, this proposes an enhanced methodology for member capacity, incorporating calculation models from three aforementioned standards. Comparative analysis demonstrates that standard provides superior predictive accuracy, validation exceeding 95% agreement. culminates specific recommendations offering critical insights redistribution mechanisms, behavior, deformation-induced patterns. These findings contribute development more accurate safer guidelines steel towers.
