In 1996, DNV introduced the limit state design method. The new code was a complete revision of the DNV 1981. DNV 1996 adopted latest research achievements and practical experience gained through most challenging pipeline projects executed (Ref. 1). DNV 1996 code was subsequently & regularly updated and renamed DNV-OS-F101.
Lifting calculation method 3. DYNAMIC FACTOR When the movement of the precast unit is performed by lifting gear, dynamic forces that depend on the lifting gear used, appear. The lifting classes are described in DIN 15018. Lifting factor f is the acceleration factor. When lifting and carrying precast elements, the lifting load has to be

A lifting beam is loaded in bending. Typically a simple lifting beam will have a single lifting eye above the beam which engages with the lifting machine hook and lower lifting eyes at points on the underside of the beam to connect to the load. A spreader, often called a spreader beam, is actually a strut loaded in compression.

Business tourism trends Adventure travel Executives are increasingly attracted to the adventure venue business trip, which combines team building and strategic planning needs with adventure travel. One company, for example, designs adventure vacations for organizations designed to boost morale and develop leadership in corporate employees, while providing a "perk" in the way of a rafting trip .
