Abstract:
Equations are presented for the calculation of the rigging geometry when the panels are tilted from the horizontal to the vertical position. The equations are presented for typical two-high, three-high, and four-high cable riggings. These equations are nonlinear. Solutions to these equations are obtained by using numerical methods. An example is solved by a computer program written especially for execution from a time-sharing terminal. The computer program determines, for any angle of panel inclination, the geometry of the rigging, the forces in the cables, and the moments and flexural stresses in the panel. This ex. ample shows that the flexural stresses va& significantly as the panel is tilted into position. The paper concluded with the recommendation that for economical erection of tilt-up wall panels a thorough flexural analysis should be done before the panels are cast.
