Resistance checks
Ultimate limit state and serviceability limit state check reports for steel joists have been implemented in the program. The option: Check (steel and timber) has been included in the “Joists” menu in the “Results” tab, which allows users to obtain the ultimate limit state and serviceability limit state checks of each joist. This option is also used to obtain the check reports of timber joists, also implemented in the 2017.a version.
Fire checks
The 2017.a version of CYPECAD includes a fire resistance check for steel joists. The data definition for the fire resistance check of steel joists in CYPECAD is the same as for steel beams in the “Fire resistance check” dialogue in the “General data” option (Project > General data > Loads > Fire resistance check). As occurs with other structural elements of CYPEAD, the required resistance and cladding (if present) for each type of structural element is defined for each floor group.
Different data can be defined in any zone of a floor group using the options in the Fire resistance floating window (Groups > Fire resistance from the Beam Definition or Results tab).
CYPECAD will carry out each resistance check at room temperature (persistent or transitory situation) and in the case of a fire, in accordance with the specifications of the code.
