What Are Log Angles and Why Are They Rarely Used?

TL;DR

Log angles are short lengths of angle sections that connect the outstanding leg of an angle, reducing joint length and shear lag. Despite their benefits in improving stress distribution, log angles are often too expensive compared to alternatives like extra connection lengths or larger gusset plates, leading to their limited use in practice.

Key Insights

• 🔺 Log angles are short lengths of angle sections used in structural engineering to connect the outstanding leg of an angle.
• 🎏 They reduce joint length and shear lag, improving stress distribution in the connected sections.
• ✋ Log angles are not commonly used in practice due to their higher cost compared to other alternative arrangements.
• 🧑‍💻 Instead of log angles, providing extra length of connection members or larger gusset plates is a more economical option.
• 🇱🇧 Log angles help minimize shear lag effect and non-uniform stress distribution in structural connections.
• 😒 The provision of log angles may be expensive compared to other connection methods, leading to their limited use in practice.
• 🧑‍💻 Understanding log angles is important in structural engineering theory, but they are not frequently encountered in practical applications.

Questions & Answers

Q: What is a log angle in structural engineering?

A log angle is a short length of an angle section used to connect the outstanding leg of an angle, reducing joint length and shear lag.

Q: How does a log angle affect stress distribution?

Adding a log angle reduces the shear lag effect, resulting in more uniform stress distribution in the connected sections.

Q: Why are log angles not commonly used in practice?

Log angles are more expensive compared to providing extra length of connection members or larger gusset plates, making them less economical to use.

Q: What is an alternate arrangement to using log angles?

Instead of log angles, providing extra length of connection members or larger gusset plates is a more economical option in practice.

Summary & Key Takeaways

• Log angles are short lengths of angle sections used to connect the outstanding leg of an angle in structural engineering.

• They reduce joint length and shear lag, improving stress distribution in the sections.

• However, log angles are expensive compared to using extra length of connection members or larger gusset plates, so they are not commonly used in practice.
