How to calculate the size of stirrups of a slope with face extended beam????? There are so many beams execute at working site, Slope with face extended beam is one of them. We are going to calculate stirrup sizes of slope with face extended beam. let's calculate the stirrup sizes of face extended beam by interpolation formula. Formula- Y=Y 1+((Y 2 - Y 1)/(X 2 - X 1))*(X 0- X 1 )                                                                                             Diagram-                                                                                                                                                                  In interpolation  we take the ratio of  (RISE/RUN). In diagram x- indicates (RUN) & y- indicates (RISE) Problem- A 1.2 m slope beam having 600 mm depth in one end & 1500 mm depth in another end, width of beam is 300 mm. 8 mm dia stirrups having 200 mm c/c. Prepare BBS of  this beam. Solution- Nos of stirrups =

Calculate quantity of cement & sand requirement for plaster????? Dear friends today we discuss about a new topic i.e. Calculate quantity of cement & sand requirement for plaster? In site work, we have to submit our requirement before our execution. So for this we calculate our requirement quantity before execution. Let's see how we calculate our required quantity of cement & sand for plaster work. Question- Area of wall is 1 sqm, mortar ratio is 1:4 & thickness of plaster is 10 mm, Calculate the quantity of cement & sand for plastering? Data given- Area of wall = 1 sqm Thickness of plaster =10 mm or 0.01 m Ratio=1:4 Solution- First we calculate our plaster volume i.e. (area of wall*thickness of plaster)                                                                   = (1*0.01) = 0.01 cum Sum of ratio = (1+4) =5           Cement              Sand  5 =        1               4  1  =.    (1/5)           (4/5) 1.33 =   

Calculation of brick masonry?????? Brick masonry is a major part in civil engineering. when we think about brick masonry a serious question always arise in our mind i.e. how we calculate our required quantity of brick for brick masonry? let's see how we calculate our required quantity of brick. Dear friends when we calculate our brick quantity we should collect 3 data, which are mentioned below in systematically, (Standard size of brick available in India)  Thickness of brick masonry  Volume of brick masonry  Size of brick These 3 factor plays a very important to calculate quantity of  brick. QUESTION - Calculate the required quantity of brick for 1 CUM? Given data- 1. Volume of brick masonry = 1 cum                     2. Size of brick = 0.19 * 0.09 * 0.09 (size in meter) Solution- Size of our brick is = 0.19*0.09*0.09(m), but when place our brick in our required area at that time we use mortar of 0.01 m for bonding. So we add this into ou

Calculating weight of test cube at site???? There are different types of test for concrete,cube test is one of them. We will cast cube in cube mould at the time of casting. Generally we take 6 nos of mould, 3 nos for 7 days test & rest 3 nos for 21 days test. Let us go for calculating weight of test cube, Before we go for calculation we should know two things, Volume of cube = 0.15 * 0.15 * 0.15(units in meter) Unit weight of p.c.c cube = 2400 KG/CUM  Unit weight of r.c.c cube = 2500 KG/CUM  Weight of p.c.c cube = 0.15 * 0.15 *0.15 * 2400 = 8.1 KG Weight of r.c.c cube = 0.15 * 0.15 * 0.15 * 2500 = 8.43 KG PLEASE SUBSCRIBE MY SITE AND COMMENTS ABOUT THE CONTENT.THANK YOU

How to calculate the percentage of steel in concrete????? Before we go for calculation we should know, what is the role of the percentage of steel in civil? Basically Percentage of steel in concrete means, the ratio of (area of steel/ area of concrete) We calculate the ratio to know, how much percent of steel we can place in concrete. Question- we are having a column of (400*300)mm & it has 6 nos of 16 mm bar. So calculate the percentage of steel in concrete? Let us know how we calculate the ratio,                                                                                     ʃ = (area of steel/ area of concrete)  ʃ = (Ast/Asc)  Ast = nos. of bar × (π/4) × square of dia                                 Ast = 6 × (3.14/4) × 16 × 16 =1205.76 sqmm Asc = Length × Width Asc = 400×300 = 120000sqmm (All bars are 16 mm) According to our formula,  ʃ = (Ast/Asc)  ʃ = (1205.76/120000)  ʃ = 0.010048 To get result in percent we have to multiplies our answer

Change unavailable dia of steel at site?? Sometimes the required amounts of steel of a particular dia are not available at site, so we have go for higher dia/ lower dia of required dia of steel. Let us calculate. Suppose we do not have 12mm at site. So we have to go for higher dia or lower dia of 12mm for our site progress. We choose 10mm as re-place bar. Question- If 12mm dia having spacing 100mm c/c, then what is the spacing for 10mm dia ? Solution Formula – (Area of available dia/ Area of un-available dia) × Given spacing         Area of 12mm bar = (π/4) × square of dia          (3.14/4) * 12 *12 = 113.097         Area of 10mm bar = (π/4) × square of dia          (3.14/4) × 10 * 10 = 78.539 According to formula = (78.539/ 113.097) × 100                   = (0.6944 × 100) = 69.44mm or say 70mm PLEASE SUBSCRIBE MY SITE AND COMMENTS ABOUT THE CONTENT.THANK YOU

How to calculate of concrete weight?????? Standard unit for concrete :- P.C.C - 2400 KG/CUM R.C.C - 2500 KG/CUM Weight of p.c.c concrete ???? *****Quantity of concrete - 5 CUM          Weight - standard unit * cum                          2400*5 = 12000 KG Weight of R.c.c concrete ???? *****Quantity of concrete - 5 CUM          Weight - standard unit * cum                          2500*5 = 12500 KG PLEASE SUBSCRIBE MY SITE AND COMMENTS ABOUT THE CONTENT.THANK YOU

How to calculate weight of steel at site ? Formula - ( D*D/162 )* R.M.L D= dia of bar R.M.L = running meter length of steel   Example- Suppose we are having 8mm steel & we have to calculate the weight of 8mm steel having length of  1 meter. Solution- ( D*D/162 )* R.M.L ( 8 * 8/162 )* 1 ( 64/162 )*1 0.395 * 1 = 0.395 KG or 395gm Always take answer value in KG PLEASE SUBSCRIBE MY SITE AND COMMENTS ABOUT THE CONTENT.THANK YOU
