## 4 Conclusions  
This study proposes an integral wall plate (IWP) structure to connect the steel anchor beam/box to the concrete pylon wall in the cable-pylon anchorage zone. The performance of the IWP was analyzed through half-scaled model tests and FE analysis of the composite pylon anchorage zone. The following conclusions have been drawn:  
* The IWP exhibits excellent stiffness and pull-out resistance, with significant tensile forces observed in the perfobond connectors. For the steel anchor beam configuration, relative deformation between the end plate and the pylon wall increased linearly with load up to 1.2 times the design load P, with no visible cracking observed below 2.5P. FE results confirm that stress levels in both the steel and concrete components remain within allowable limits. In the steel anchor box configuration, the IWP secures the steel anchor box utilization at 74% and reduces the principal tensile stress on the outer pylon wall by approximately 1.5 MPa, with stresses vanishing beyond 0.6 times the wall thickness--unlike conventional internal or exposed types.
* The IWP design promotes consistent and efficient force transfer through the combined action of end, side, and surface plates. Perfobond connectors primarily experience unidirectional shear, with longitudinal-to-vertical shear ratios remaining below 0.21. Parametric studies reveal that connector arrangement, perforated hole diameter, and side plate thickness significantly affect the distribution of vertical and shear forces. Increasing end or surface plate thickness slightly reduces anchor box utilization and tensile stress in the pylon wall, which can be beneficial for optimizing design against fatigue effects in long-term service.
* This study is based on a down-scale model experiment. Scaling effects and simplified boundary conditions may influence accuracy in real applications. Future work should include FE simulations incorporating detailed wall reinforcement, dynamic loading,

and long-term fatigue and creep effects. These would offer more comprehensive guidance for practical design standards, especially for large-scale bridge pylons subjected to high cable forces.
