Summary:
When a bending member has a tall and slender cross-section and is asymmetric (Ixy ≠ 0), there will be significant lateral deflections. This will be explained using advanced mechanics of materials principles. A cross-section based on typical L-Spandrels used in prestressed concrete garages will be analyzed as an example. The analysis will also include asymmetric shear, and torsion of thin rectangles. These effects are secondary to the asymmetric bending.
Conclusions from this work are:
・Asymmetric members (non-zero Ixy) with large Iyy and small Ixx will have large lateral deflections under vertical load.
・Symmetric members (Ixy=0) with large Iyy and small Ixx will have large lateral deflections under loads that are slightly off of vertical.
