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...
Explicit solutions to vertical and horizontal displacements are derived for large deformation of a cantilever beam under point load at the free end by an improved homotopy analysis method (IHAM). Quadratic cubic nonlinear differential equations adopted construct more proficient respectively combined with their currently available displacement equations. Higher-order iterative established solve combining simultaneous constructed auxiliary linear The convergence range is extended homotopy-Páde...
An improved homotopy analysis method (IHAM) is proposed to solve the nonlinear differential equation, especially for case when nonlinearity strong in this paper. As an application, was used derive explicit solutions rotation angle of a cantilever beam under point load at free end. Compared with traditional method, derivation includes two steps. A new equation firstly constructed based on current and auxiliary quadratic equation. In second step, high-order non-linear iterative established...

The smoothed finite element method (S-FEM) has been found to be an effective solution for solid mechanics problems. This paper proposes approach compute the lower bound of free vibration and upper forced structures, by making use important softening effects node-based (NS-FEM). Through gradient smoothing technique, strain-displacement matrix is obtained in domain based on mesh nodes. Subsequently, stiffness computed a manner consistent with standard (FEM). Here, practical Lanczos algorithm...
