TABLE 3 – Load Capacities Developed by Structural Analysis
Mar 31, 2017
| Basic Frame | With Extension Legs** | ||
| Capacity* lb/leg | 8″ ext. | 14″ ext. | |
| Vertical @ S.F. – 2.5 | 6,800 | 5,000 | 4,000 |
| Lateral @ S.F. – 2.5 | 136 | 100 | 80 |
| Vertical @ S.F. – 2.5 | 8,700 | 6,000 | 4,400 |
| Lateral @ S.F. – 1.0 | 174 | 120 | 88 |
| NOTE: Where lateral loads to be resisted are less than 2%,the vertical capacity may be adjusted pro-rata. * With 12″ screwjack extended top and bottom. ** At either or both ends, plus 12″ screwjack extension each end. NOTE: In general, the longer extensions may be eliminated by appropriate combinations of standard frame heights. NOTE: Where lateral loads are imposed, the designer must also consider: a) Stability of the incomplete and completed structure against overturning. b) Additional vertical loads induced in resisting lateral loads. c) Drift (lateral deflection) under lateral loads, which may affect forming tolerances. |
