Floor Area Ratio (FAR) কিভাবে বের করবেন ?

 Floor Area Ratio (FAR) কিভাবে বের করবেন ? 


এখুনি হিসাবটা শিখে নিন .আমরা যারা ইঞ্জিনিয়ারিং  তাদের FAR জানা  দরকার ।

ধরুন, আপনার 6 কাঠা জমি রয়েছে। ভেবে রেখেছেন 8-10 তলা উঁচু বাড়ি বানাবেন । 

কিন্তু আপনি জানেন কি ?

আপনি চাইলেও 6 কাঠা জমিতে ১০ তলা বানাতে পারবেন না রাজউকের নিয়মানুযায়ী ।

 কারন একটা ভবন বানানোর সময় বিল্ডিং এর চারপাশে কিছু জায়গা ছেড়ে দিয়ে তারপর ডিজাইন করতে হয় । সেটাকে (Setback) সেটব্যাক বলে । 

আমরা শুধুমাত্র ফার নিয়ে আলোচনা করবো ।

FAR জানার সুবিধাঃ

১. FAR জানা এক জন সিভিল ইঞ্জিনিয়ারিং খুব দরকার।

২. বাড়ি কত তলা করতে পারবেন সেটা নিজেই হিসাব করতে পারবেন অংক করে ।

FAR এর হিসাব করবেন যেভাবেঃ

মনে করি,

ভূমি- ৬ কাঠা,

রোড- ২০ ফুট,

FAR- ৩.৫

Maximum Build Area (M.B.A) = Land x Far

= 6 katha x 3.5 (far 3.5)

= 6720) x3.5 (1 katha=720square ft)

= 4320×3.5

=15120 Sqft

Maximum Ground Coverage (M.G.C)- 62.5%

= 6 katha x 62.5%

= (6x 720) x 62.5%

= 2700 Sqft.

Number of Floor (N.O.F) =Maximum Build Area (M.B.A) / Maximum Ground Coverage (MGC)

= 15120 / 2700

= 5.6 Floor

Total Floor = Ground floor + 5.6 floor

= 1+ 5.6 floor

= 6.6 floor ( ৬ তলা বাড়ি এবং চিলেকোঠা) ।

এই হিসাবে প্রায় সাত তলা  করতে পারবেন।

Live Load Calculation Bangladesh National Building Code (BNBC) 2020

 Live load is calculated According to the Type of building Bangladesh National Building Code (BNBC) 2020 Bangladesh National Building Code (BNBC) 2020 , live loads refer to the loads that are not permanently attached to the structure. These loads are important for the design and structural integrity of buildings. The live load values are specified depending on the type of building use and occupancy. Here’s a table with typical live load values in PSF (pounds per square foot) and kN/m² (kilonewtons per square meter) based on common building usages, as per the BNBC 2020 or similar standards: Live Load - BNBC 2020 Sl Occupancy or Use Live Load (Psf) Live Load (KN/m²) 01 Roofs (ordinary) 20 0.96 02 One and two-family dwellings 40 1.92 03 Apartment buildings, dormitories, hotels 40 1.92 04 ...

Using the 3-4-5 Method of Building Layout

Image
Why does the building layout follow the 3-4-5 Method? Identify a Base Line: 1. Start by marking a baseline along one edge of the area where the right angle is needed. For example, this could be the edge of a foundation or a wall. Measure Along the Base: 2. From one end of the baseline, measure 3 units along this line. Mark the end of this measurement as Point A. Measure Perpendicular Line: 3. From the same starting point (Point O), measure 4 units at approximately a 90-degree angle to the base. You can use an adjustable square or approximate the angle by eye. Mark the end of this measurement as Point B. Check the Hypotenuse: 4. Measure the distance between Point A (on the baseline) and Point B (on the perpendicular line). If the distance is exactly 5 units, then the angle between the two lines is a perfect 90-degree angle. By following these steps, you can quickly and accurately establish a square layout for building foundations or other construction projects.
