High mast illumination poles (HMIPs) experience cyclic loading from wind, which can cause large deflections at the top of the pole, amplified by the mass and geometry of the luminaire. As a result, large stresses can develop at the handhole and base plate connections. These details are especially susceptible to fatigue cracking due to the combinati
