American Concrete Design

STAAD currently provides facilities for designing 3 types of 
entities associated with surface type of structures. 
 

a.  Individual plate elements – these are designed from the 

standpoint that one element is independent of the next 
element. See section 3.8.1 for details. 

b.  Shear Walls – Structural components modelled using the 

SURFACE INCIDENCE command can be designed as 
shear walls. See section 3.8.2 for details. 

c.  Slabs and RC Designer – STAAD has the facility for a 

full-scale slab design. This is called the RC Designer, and 
details are available in section 3.8.3. 

Element design will be performed only for the moments MX and 
MY at the center of the element. Design will not be performed for 
FX, FY, FXY, QX, QY 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 in Table 3.4. 
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 (Figure 3.1). 
The parameters FYMAIN, FC, and CLB (CLEAR) listed in Table 
3.1 are relevant to slab design. Other parameters mentioned in 
Table 3.1 are not applicable to slab design.
