D8.E.8 Element Design
Element design will be performed only for the moments MX and MY at the center of the element. Design will not be performed for SX, SY, SXY, SQX, SQY, or MXY. Also, design is not performed at any other point on the surface of the element.
A typical example of element design output is shown below. The reinforcement
required to resist Mx moment is denoted as longitudinal reinforcement and the reinforcement
required to resist My moment is denoted as transverse reinforcement (Refer to D8.E.1 Section Types for Concrete Design). The
parameters FYMAIN
, FC
, and CLEAR
listed
in D8.E.3 Design Parameters are relevant to slab design.
Other parameters mentioned in the design parameters table are not applicable to slab design.
