(a) (b) Fig. 3. (a) Arch structure with sand loading; (b) loading variation curve on the structure.

The displacement profile of these loading distributions is shown in Fig.5. It is worthy of note that the displace ment at the top point of curve frame is going upward when the loading is applied perpendicular to the surface of elements. Another observation is that the locations of maximum curvature are the same for both loading scenarios.
