How to Calculate Cutting Length for Circular Stirrups | Afroz Civil How to Calculate Cutting Length for Circular Stirrups (Step-by-Step) In RCC construction, accurate cutting length of circular stirrups is essential for proper reinforcement detailing, cost control, and smooth site execution. This guide explains the cutting length calculation for circular column stirrups with a clear and practical example. Given Data Diameter of circular column (D) = 900 mm Clear cover = 40 mm Diameter of stirrup bar (d) = 10 mm Shape = Circular stirrup Hooks = 2 hooks (standard) Bend Criteria (As per Site Practice) 45° bend = 1d 90° bend = 2d 135° bend = 3d Standard hook length = 10d Where d = diameter of stirrup bar. Step 1: Effective Diameter of Stirrup (D 1 ) D 1 = D − 2(Clear Cover) − 2(Half stirrup diameter) D 1 = 900 − 2(40) − 2(10/2) ...

Guide to Understanding Building Drawings By Afroz Civil Building drawings are essential documents that communicate the design, dimensions, structure, materials, and technical services of a building. This guide provides a complete understanding of how to read building drawings effectively from both architectural and structural perspectives. 1. Understanding Dimensions & Scale Dimensions Dimensions represent width, height, depth, and spacing between elements. Architectural drawings use dimensions to locate rooms, doors, windows, and finishes. Structural drawings use them to fix foundation sizes, reinforcement cover, beam spans, and slab thickness. Scale Drawings are scaled representations of real objects. Architectural drawings typically use: 1:100 for plans 1:50 for detailed layouts Structural drawings often use: 1:20 for reinforcement detailing 1:10 for complex joints or connections 2. Important Abbreviations Used in Drawings Includes architectural, st...
