EXAMPLE 7. VALUATION OF A BUILDING FROM LOAD-BEARING MASONRY

EXAMPLE 7: 'VALUATION OF A MASONRY BUILDING' 41 5.2 Checking load-bearing masonry based on stress criterion In load-bearing masonry structures it is often useful to check the adequacy in terms of stresses. This check is performed on structures with walls of any shape (curved or flat) and applies to both existing and new masonry. The criterion that has been incorporated into SCADA Pro is Karantoni et al (1993) which has the following form: 2 √ 2 1 = 2 + + − 1 where ≥0 indicates failure and <0 indicates adequacy. 5.2.1 Set Material Parameters The Karantoni et al (1993) criterion, in addition to the parameters related to the simulation, requires the definition of the following material strengths: • Compressive strength ( fw ) • Tensile strength ( fwt ) • Equal biaxial compression strength ( fwcb ) These strengths are defined in the masonry library for the materials used.
