10 +**Concealed bar** is a new RC design object that allows for designing certain parts of a shell as a bar. For example, a wall region over a door opening can be considered as a concealed beam.

25 +New concealed bar can be defined in //Specify concealed bar//. Definition steps:
26 +
27 +* Select an RC slab or wall
28 +* Specify the diagonal corners of a rectangular region, or select an existing rectangular region
29 +
30 +(% style="text-align: justify;" %)
31 +The bar’s local co-ordinate system by default is parallel with the region’s local system, but there is an option to define skew concealed bars.

41 +Manual and automatic design process for concealed bars is the same as for individual RC bars. Listed tables and displayed results are also similar, but concealed bar’s internal forces - derived from the shell’s internal forces - are also listed and displayed.
