Many of us have seen and experienced the “Sunflower Effect”. Most of us remember the first time we pulled up to a monopole and saw a severe case of it. It seems as if the pole is leaning or is damaged in some way. However, upon further assessment it appears that there is no damage and as the day goes on the pole seems to magically straighten out, almost as if the pole has a mind of its own. Why is this happening, does it cause harm to the structure, can it be avoided? This PAN seeks to address these questions and raise awareness about the thermal growth effect of steel.
