Hello everyone! The working season almost ends. Time to sum up! For new readers: The task was to create a concrete slab for basement floor of 12x15m house in Russia. At the beginning of season we just had basement walls and bar releases (see attached photoes at the beginning). During summer the floor slab was filled in, waterprofing and thermal insulation of basement walls were finished Now, It is the good opportunity to show obtained results. Maybe someone will find something them interesting. I would not say that we completely followed by advices from this forum, but still, all suggestions were considered. Thanks everyone who answered, espesially big thanks for Badar! There is video how we bend bars. We did a "special" machine for this operation Grid pitch (step) is 200 mm in some places it is only 100 mm Slab height is 210 mm I wrote everything briefly, but if there are questions, I can add! video_2022-10-18_12-05-29.mp4

EngrJunaid, What you are doing is not enough. You need to make sure your walls are designed for axial load + out of plane bending & in-plane shear + bending. Also design requirements for roof diaphragms should be incorporated and serviceability limit states should be checked.. I would recommend you to get a good reference book at-least. I personally use Masonry Structures: Behaviour and Design There is so much in masonry that would be new to you. Like Mortar Types, Concepts about 1) Vertical and horizontal load transfer, 2) Distribution of Shear and Moment due to Lateral Load, 3) Torsional Effects etc. and most importantly 4) Masonry Shear Walls. If you know how to design one, you can save your client a lot in Pakistan since no one is focusing on building low-rise (up to 10 stories) masonry buildings. Thanks.

In general, yes. However, be careful to check other requirements (especially minimum sizes & reinforcement of confining members, with reference to wall density) for confined masonry design, as given in the document referred in para 1-b of my previous post, and the following guideline (more recent): http://www.world-housing.net/wp-content/uploads/2011/08/ConfinedMasonryDesignGuide82011.pdf Regards.

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.
