Hi! Can you help me compute the concrete and masonry works for this structure based on the attached elevation drawing?The image shows the side view of a small building with labeled sections, wall openings (windows), and dimensions in centimeters.
Specifically, I need help computing the following:
For Concrete Works:
Volume of concrete for footings, columns, and slab (if applicable)
For Masonry Works (CHB Walls):
Total wall area (excluding window openings)
Number of CHBs required (based on 0.4 m x 0.2 m CHB)
Cement and sand for block laying
Cement, sand, and gravel for core filling (if reinforced)
Cement and fine sand for plastering (both sides)
Rebars needed for CHB reinforcement (if any)
Please base it on the drawing dimensions. Let me know if additional assumptions or standards are needed (e.g., CHB size, mix ratio, thickness of plaster). Thank you!
Hi! Can you help me compute the Masonry Works for the 3rd Floor only based on this image?This image shows all my completed concrete, rebar, slab, and formwork computations for the 3rd floor of a 3-storey residential building.
Specifically, I need the following for CHB walls:
Quantity of CHB
Cement & sand for block laying (mortar)
Cement, sand, and gravel for core filling
Cement & fine sand for plastering
Cement, sand, and gravel for CHB wall footing
Number and length of vertical & horizontal rebars (10mm or as required)
P16.11 WP An assembly consisting of tie rod (1) and pipe strut (2) is used to support an 80 kip load, which is applied to joint B. Strut (2) is a pin-connected steel [E = 29,000 ksi] pipe with an outside diameter of 8.625 in. and a wall thickness of 0.322 in. For the
loading shown in Figure P16.11, determine the factor of safety with respect to buckling for member (2).
