PRESTRESSED CONCRETE BOX - GIRDER

File name is PRESTRES. Computer Program. Design and Analysis of prestressed concrete Box-Cirder (Single or double box). Design version: Input: 1. Dimensions of Box-Girder cross section. 2. Type of prestressing strands path, span length and loads data. 3. Location of diaphragms and hold down points and prestr. strands characteristics. 4. Strength of concrete and prestr. steel and stirrups characteristics. 5. Number of sections to be analyzed, location and LL Moment for each sect. Output: 1. Area of cross section and Moment of Inertia. 2. Stresses at extreme fibers due to external loads. 3. Number of strands required and location of controid at mid-span and support. 4. Extreme fiber stresses for initial prestress, full DL and total load. 5. Ultimate moment required and number of strands needed to provide this moment at various concrete strengths. Analysis version: Additional input: Number of alternatives and number of strands and location of centroid at mid-span and end sections for each alternative. Output: for each alternative. 1) Extreme fiber stresses at initial prestress full DL and Total load. 2) Ultimate Moment provided. 3) Required stirrup spacing at 1/4 and 1/3 span points. 4) Deflections under DL and LL.
