Composite wall structural design requirements are contained in building code requirements for masonry structures ref. We have enjoyed over 25 years as one of the top foundation repair specialists in los angeles. This is for the protection of you the home owner. A wall utilized to resist the required seismic forces not including crosswalls.

Check fully grouted reinforced concrete masonry wall design and partial grouted concrete masonry wall with neutral axis in the face shell subjected to flexural stresses only for bending stress. An exterior building wall plane without a shear wall adequate to resist the required lateral forces. An unreinforced masonry building or umb urm building is a type of building where load bearing walls non load bearing walls or other structures such as chimneys are made of brick cinderblock tiles adobe or other masonry material that is not braced by reinforcing material such as rebar in a concrete or cinderblock. Minimum design load is 5 psf out of plane sds 0 5.
