Contract Awarded for Manufacturing and Transportation of Precast Concrete Parabolic Segment
(PCPS), Panel and Lid for Zer Gul, Janat Gul, Sangeen, Mia, Zafran and Kozawalia Irrigation Schemes in Qarghai, Khewa and Noor Gal districts of Laghman, Nangarhar and Kunar provinces.
When the obstacles are polygons, the Voronoi diagram consists of straight and parabolic segments
Two span beam with uniformly distributed loading A two span beam of 30 m span and 300mmX750mm cross section with 23 KN/m uniformly distributed loading (including self weight) and prestressing force of 938 KN has been analyzed by load balancing method with idealized parabolic profile and by Lin's method [Lin and Burns (1995)] with actual cable profile considering two parabolic segments at midspan and two reversed parabolic segments at the support (Fig.
The analysis considering two parabolic segments at midspan and two reversed parabolic segments at support, is very complex.
Stresses obtained by modeling the cable by 6 parabolic segments (Lin's approach) are different than due to two parabola.
