53 Two new kinds of Stud punching reinforcements are implemented in FEM-Design 18: **General **and **PeikkoPSB** product. They differ only in their calculation method. For automatic design the following design parameters can be set.

101 **No shear region** object is implemented for RC plates. It makes it possible to define regions, where shear can be ignored.

103 (% style="text-align: justify;" %)
104 When entering RC tab, automatic //No shear// regions are generated for RC plates,
105

107 * along wall intersection lines
108 * at point and line supports.

110 (% style="text-align: justify;" %)
111 Width of these regions depends on plate thickness and a factor that can be modified. One can also edit or inactivate these regions, but they cannot be completely deleted. (% lang="EN-US" style="font-family:~"Open Sans Light~",sans-serif; font-size:11pt; line-height:107%" %)User can also define //No shear region//s manually by launching //No shear region// command.
