MasterFrame: Concrete Slab Deflection and Cracking - Overview

The Concrete Slab Deflection and Cracking design is an extension to the MasterFrame: FE Slab Design module. The FE Slab Design module allows users to automate the design of concrete slabs analysed as FE surfaces within Masterframe. The Deflection and Cracking module then allows the user to utilise the reinforcement design to then carry out an additional analysis on the slabs to directly calculate the long term deflection of the slab taking into account the effects of creep, cracking and shrinkage. The Concrete Slab Deflection and Cracking design allows the user to create time dependent loading events, such as striking of the concrete, construction loading, partition erection and final live loading and to assess the effects that these have on the cracking and deflection of the slab. The design then gives outputs of the deflections at each time step along with crack ratios to indicate the extent of cracking in graphical outputs which can be exported as part of a design report. The software then gives outputs of the long term deflections of the slabs.

In addition to the calculation of the long term deflection, the module also calculates the maximum crack widths in accordance with EC2.
