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