Two independent structural finite element models were developed one by the designer and another by the erector. |
So he went to night school to study engineering and became a steel erector. |
To erect the trusses, the steel erector used twelve 78-ft-tall shoring towers, one under each tip of each cantilever. |
Close-grip work also helps improve posture and body carriage by strengthening the mid-back muscles, rhomboids and erector spinae. |
When the erector muscle contracts, the outer coat hairs stand up to trap the air and cause pressure on the sebaceous gland releasing the suint. |
The erector then used the trichord's upper chords to support a work platform for the arch. |
