OPERATIONAL EXPERIENCE WITH PRESTRESSED CONCRETE BARGES
Describes the economics, construction and operation of prestressed concrete hulls that would meet the requirements for lightship weight and draft which would allow higher deadweight to displacement ratios within the limits of the navigational depths and bridge clearances in the Pasig River and other waterways in the Philippines. The final hull structural design arrived at from this research involved framing with a series of transverse structural steel frames supporting a 4-1/2 inch thick pretensioned prestressed concrete outer shell. Compartmentation and bulkheading were framed with conventional steel plating and structural shape stiffeners. The 4-1/2 inch thick concrete shell is prestressed longitudinally to develop the overall hull bending moments and local bending moments, and this shell is attached to the structural steel framing by means of welded shearlugs which were installed on the steel framing prior to the concrete shell pour. Both transverse and longitudinal convertional unprestressed reinforcing steel and wire mesh were added to the concrete shell for additional local and bending and impact resistance.
