At a swim meet, I noticed a whole row of people leaning against the railing at the upstairs part of the Indoor Aquatic Center. How much weight is that railing designed to bear?
Andy Pitts of Treanor Architects, PA said: "The guardrail for this project was designed around the requirements of the Uniform Building Code, as adopted by the city of Lawrence. ... Based on the engineer's calculation, the 2-inch thick, fully tempered glass will support a lateral load of 6,000 psi (pounds per square inch), above the lateral load of 4,200 psi outlined by the Uniform Building Code."
That's strong enough to bear the weight of many more people than would fit in the space.
