Practical examples and case studies further illustrate the application of these principles in real-world scenarios.
4.3 Triangular Distribution Method
The triangular distribution method is one of the four approaches outlined in AISC Design Guide 1 for calculating base plate thickness. This method assumes a triangular stress distribution across the base plate, simplifying the analysis by focusing on the maximum stress at the plate’s edge. It is particularly useful for cases where the load is applied eccentrically, as it accounts for the resulting moment and shear forces. The method ensures that the bearing pressure on the concrete foundation does not exceed its capacity while maintaining the plate’s structural integrity. By using this approach, engineers can efficiently design base plates for both compressive and tensile axial loads, ensuring safety and cost-effectiveness. This method is especially practical for complex load conditions and is widely adopted in steel construction projects.
Bolted Connections in AISC Design Guide 1
Bolted connections are critical in steel construction. AISC Design Guide 1 covers types of bolts, washer requirements, and design considerations for snug-tight, slip-critical, and bearing connections.
5.1 Types of Bolts
In AISC Design Guide 1, bolted connections are categorized based on their behavior under load. The primary types include snug-tight, slip-critical, and bearing-type connections. Snug-tight bolts are tightened to a snug condition, providing a small clamping force without slip resistance. Slip-critical connections rely on the friction between the bolt and connected parts to resist loads, requiring pre-tensioning. Bearing-type connections transfer loads through the bolts and rely on the shear strength of the bolt. The guide specifies ASTM standards for bolts, such as ASTM F3125 for structural bolts, ensuring proper material and strength requirements. Additionally, washer requirements are emphasized to prevent bolt head pull-through and ensure even load distribution, particularly for larger or high-strength bolts.
