Punching Shear Analysis Caused by Wind Loads on Small Traffic Signs

Abstract

Abstract - Small traffic signs are the most typical type of traffic signs encountered throughout the streets and roads. Since Puerto Rico is located in a hurricane prone region, is reasonable to ask if these traffic signs could withstand the design wind loads established by the current codes and if the existing different types of plate-to-post connections are safe. To accomplish the investigation, laboratory experiments were conducted to verify the resistance to punching shear on sign plates. Results were compared to design calculations obtained from codes. It was observed that the different types of connections evaluated have the required strength to withstand design wind loads. Key Terms - Punching, Shear, Traffic Sign, Wind Loads.
