SS-V: 1080 Scordelis-Lo Roof

Test No. VS09 Find the maximum Z displacement for a curved cylindrical dome.

Definition

Figure 1.

The dome is supported on curved edges (Ux, Uz = 0) and unconstrained on straight edges. Due to symmetry, only 1/4 section was analyzed (Figure 1).

The load is -90N/m² in -Z direction.*

The model parameters are:

Parameters: Value
L: 50m
R: 25m
t: 0.25m

The material properties are:

Properties: Value
Modulus of Elasticity: 4.32e+8
Poisson's Ratio: 0.0

Results

The following table summarizes the displacement results.


	Theory**	SimSolid	% Difference
Maximum Z Displacement [m]	3.0860E-01	3.1098E-01	0.77%

*To determine the Z-load: Area of top face is 2*Pi*(R+.125)*(40/360)*25 = 438.514 m². To get -90 N/m², you need a total load of 438.514*90 = 39466.25704 N.

**The theoretical solution value of the Z displacement at the middle of the free edge is given as 0.3086, though many finite element codes converge to the smaller value of 0.3024.
