TY - JOUR PY - 1983// TI - Development of safer utility poles JO - Transportation research record A1 - Labra, J.J. A1 - Kimball Jr., C.E. A1 - McDevitt, C.F. SP - 42 EP - 53 VL - 942 IS - N2 - This paper is based on a FHWA-sponsored research program to develop a breakaway retrofit concept for roadside timber utility poles. Southwest Research Institute's efforts to achieve this goal are described. The research included analytical (simulations) as well as experimental efforts. The experimental efforts involved static bending tests, pendulum tests, and full-scale tests of poles with subcompact automobiles. A slip-base concept, called Slipbase, is recommended for implementation along roadsides. Slipbase is capable of reducing significantly the inherent roadside hazards associated with in situ timber utility poles while maintaining a high level of wind-ice resistant bending strength. The slipbase concept cannot be applied universally at this time because no tests have been conducted on poles that carry multicircuit electric lines or on poles that carry joint electric and telephone lines.
