If you will put on-site additional reinforcement only at bottom, then just do like what your engineer said (Tension=0.0095 and Compression=0.00256) If you are going to put additional reinforcement on both sides then put 0.0095 on both sides in SAFE. Having said that, you should know that compression (top) reinforcement helps reducing deflections. So put top reinforcement to control deflections.

Junaid, 1. If you go through the following threads, you will find several good references on the subject: a. http://www.sepakistan.com/topic/1652-load-bearing-structure-design/?hl=masonry#entry4141 b. http://www.sepakistan.com/topic/1326-seismic-design-guide-for-masonry-buildings/?hl=masonry c. http://www.sepakistan.com/topic/1313-modulus-of-elasticity-of-brick-masonary/?hl=masonry#entry2495 d. http://www.sepakistan.com/topic/1680-the-seismic-performance-of-rcc-frame-buildings-with-masonry-infill-walls/?hl=masonry 2. In case of a 3-story house, it would be better to use a framed or confined masonry structure, if the structure would be constructed in a location of seismic zone 2 or higher. Moreover, you would be requiring RC walls too, for the basement portion. Regards.
