Software Verification PROGRAM NAME: REVISION NO.: SAFE METHODOLOGY A comprehensive series of test problems, or examples, designed to test the various analysis and design features of the program were created The results produced by SAFE were compared to independent sources, such as hand calculated results and theoretical or published results The comparison of the SAFE results with results obtained from independent sources is provided in tabular form as part of each example To validate and verify SAFE results, the test problems were run on a PC platform that was a HP Compaq dc7100 machine with a Pentium processor and 2.0 GB of RAM operating on a Windows XP operating system ACCEPTANCE CRITERIA The comparison of the SAFE validation and verification example results with independent results is typically characterized in one of the following three ways ¾ Exact: There is no difference between the SAFE results and the independent results within the larger of the accuracy of the typical SAFE output and the accuracy of the independent result ¾ Acceptable: For force, moment and displacement values, the difference between the SAFE results and the independent results does not exceed five percent (5%) For internal force and stress values, the difference between the SAFE results and the independent results does not exceed ten percent (10%) For experimental values, the difference between the SAFE results and the independent results does not exceed twenty five percent (25%) ¾ Unacceptable: For force, moment and displacement values, the difference between the SAFE results and the independent results exceeds five percent (5%) For internal force and stress values, the difference between the SAFE results and the independent results exceeds ten percent (10%) For experimental values, the difference between the SAFE results and the independent results exceeds twenty five percent (25%) The percentage difference between results is typically calculated using the following formula: Percent Difference = 100 SAFE Result -1 Independent Result METHODOLOGY - SUMMARY OF EXAMPLES Examples through verify the accuracy of the elements and the solution algorithms used in SAFE These examples compare displacements and member internal forces computed by SAFE with known theoretical solutions for various slab support and load conditions Examples through 14 verify the applicability of SAFE in calculating design moments in slabs by comparing results for practical slab geometries with experimental results and/or results using ACI 318-95 recommendations Design examples verify the design algorithms used in SAFE for flexural, shear design of beam; flexural and punching shear of reinforced concrete slab; and flexural design and serviceability stress checks of post-tensioned slab, using ACI 318-08, AS 3600-01, BS 8110-97, CSA A23.3-04, Eurocode 2-02, Hong Kong CP-04, IS 456-00, NZS 31-01-06 and Singapore CP65-99 codes, by comparing SAFE results with hand calculations METHODOLOGY -
