The CAPS (Precompressed) programme enables the analysis, calculation, design and verification of: - prestressed prestressed beams - beams with generic sections - beams with variable sections (total compression partial compression).‎ The most frequently used cross-sections are: rectangular, T-section, double T-section, inverted T-section, U-section, tegular, Y-section.‎ CALCULATION METHODS Performs the calculation taking into account the tension drops in the cables due to the phenomena of elasticity, shrinkage and viscosity in the concrete, relaxation in the steel.‎ Performs the calculation of the beam during its various life phases: cutting of cables, transport, lifting in place).‎ INPUT DATA- Definition of travelling load conditions to simulate possible mobile loads - Insertion of prestressing cables with generic layout - Definition of the mechanical characteristics of the prestressing reinforcement (wires, braids and strands) - For the design of the reinforcement, setting of: cover, diameter of reinforcement rods, minimum percentage of reinforcement in tensioned and compressed zone OUTPUT RESULTSd analysis concluded CAPS (Prestressing) allows the display of: - Verification for stresses - Verification for flexural failure - Verification for shear failure - Verification for cracking - Verification of any supplementary cast-in-place - Insertion of concentrated or distributed loads with linear trend - For each combination, it is possible to display the stresses induced by prestressing and those resulting from the acting loads.‎ STANDARDS- NTC 2008 (Technical Standards for Construction) and its supplements - D.‎M.‎ 88 + D.‎M.‎ 96 - NTC2018 - Circular 21 January 2019 no.‎7 C.‎S.‎LL.‎PP
