BOLTED CONNECTIONS – I

influence the calculation of the effective length for the buckling analysis of struts. The connections provided in steel structures can be classified as 1) riveted 2) bolted and 3) welded connections. Riveted connections were once very popular and are still used in some cases but will gradually be replaced by bolted connections.

Chapter 5 Footing Design - Engineering

5. If P/A exceeds M/S, then the maximum bearing pressure equals P/A + M/S and the minimum bearing pressure equals P/A-M/S. 6. If P/A is less than M/S, then the soil bearing pressure is as shown in Fig. 5-1. Such a soil bearing pressure distribution would normally be considered undesirable because it makes the footing structurally ineffective.
