Lecture # 10 of Reinforced concrete design Covers the following. In, this Lecture, I have demonstrated the difference in design approach of beam and column that i.e. the design approach of beam when subjected to bending moment only and design approach of column when subjected to combine axial and bending moment. What is Torsion in beam? and its types i.e. Equilibrium Torsion and Compatibility Torsion. What is Skin reinforcement in Concrete Beam? Why do we provide closed shear reinforcement in beam? Axial reinforcement in beam? Flexural reinforcement in beam? Shear reinforcement in Beam? Why 0.1fc’Ag is an important parameter in beam design? Should we Design Beam as Beam or as Column? # Beam Design # Columndesign # RCCDesign

Understanding the behavior of rigid frames is crucial for structural analysis and design. 🚀 This post explores two-dimensional rigid frames, focusing on the mechanics of moment-resisting joints. When members are rigidly connected, they transfer three forces: axial force, transverse force, and moment. These three unknowns per member and the equilibrium equations provided by the joints form the foundation of analyzing rigid frames. In the next slides, we've demonstrated: How to calculate stability and static determinacy. The process of using joint equilibrium equations. Examples of statically determinate and indeterminate structures. By breaking it into simple steps, this post aims to demystify rigid frames and help engineers master their analysis. Let us know your thoughts or questions below! How do you approach solving rigid frames in your designs?👇 #EngineeringConcepts #StructuralAnalysis #RigidFrames #EngineeringEducation #Eigenplus

Sawtooth staircases are waist-less designs with a modern zigzag pattern that combines visual appeal with structural complexity. Unlike traditional staircases, their unique geometry requires careful analysis to account for non-linear load paths, bending moments, and shear forces. This article explores analytical methods, including strain energy principles and advanced techniques like FEA, to address these challenges. It highlights Reynolds and Steedman’s practical approach and includes a detailed worked example using Eurocode 2, covering load analysis, moment calculation, and reinforcement design. 👉 [https://lnkd.in/dm8PMRKF] #SawtoothStaircases #StructuralDesign #StaircaseEngineering #ReinforcedConcrete #InnovativeStructures

ETABS is highly effective for analyzing structural elements like beam forces, stresses, bending moments, and shear forces. In design mode, it calculates the necessary area of steel for both flexure and shear. However, I'm curious—does this calculation take deflection into account, or should we check deflections separately? Keen to hear your thoughts!

Do you know you can align multiple views in a Tekla drawing sheet with just two points? One of the common problem is aligning views one by one and it is a time consuming task. But we have no option and that's what detailers do. How about we can select multiple views and align them quickly with two points. You may think, how it is possible. Yes. we have developed an application. Here is the demo. #TeklaStrutures #Project #Fabrication

Failure In RCC Beam: Flexure Failure Vs. Shear Failure

In structural engineering, analyzing how beams handle different types of loads is crucial. One common setup for such analysis is the four-point loading system. Here’s how it works: Setup: A beam is supported on both ends and loaded at two points, each equidistant from the nearest support. This arrangement creates two points of loading, each a third of the way across the span, splitting the beam into three segments. Purpose: This test primarily investigates the beam's response in the "pure bending zone" — the region between the two loads where shear force is constant, and bending moment is maximal. This allows engineers to study the bending stresses free from the influence of shear. This method is invaluable for predicting the structural integrity and lifespan of materials used in everything from simple engineering projects to complex architectural endeavors. 🔍 Engineers, how have you applied similar analyses in your projects? What insights have you gained about material behavior under load? #StructuralEngineering #MaterialScience #EngineeringEducation

Understanding two-way slabs can be quite challenging during undergraduate studies. This animation simplifies it by focusing solely on the flexural reinforcement, making it easier to grasp the concept. Key points: - Only flexural reinforcement is shown for clarity. - Bent-up bars are included for detailing. - Shear reinforcement, often not a part of slab reinforcement, is not depicted here. This approach provides a clear visual understanding of how reinforcement is placed to resist bending moments in two directions, essential for two-way slab design. Let’s make learning structural concepts simple and intuitive! #StructuralEngineering #ReinforcementDesign #TwoWaySlab #CivilEngineering #EngineeringEducation #BuildingDesign #Eigenplus

𝐖𝒉𝒂𝒕 𝒊𝒔 𝑻𝒉𝒆 𝑹𝒆𝒂𝒍 𝑭𝒖𝒏𝒄𝒕𝒊𝒐𝒏 𝑜𝒇 𝑎 𝑺𝒉𝒆𝒂𝒓 𝑾𝒂𝒍𝒍? Is it just another wall in the building, or does it serve a greater purpose? 🏢 Many young engineers can tell you that shear walls resist lateral forces like wind and seismic loads. But is that the whole story? 🤔 🔍 Let’s dig deeper: Not All Walls Are Shear Walls: Just because a wall is made of reinforced concrete doesn’t mean it qualifies as a shear wall. It must behave as one to provide lateral load resistance. Understanding IS Codes: Many believe that if a wall's length-to-thickness ratio exceeds 4, it’s automatically a shear wall. But this only indicates ductility, not definition! Position Matters: The ideal placement of shear walls is crucial. If they’re not positioned correctly, they may induce torsion during seismic events, leading to potential failure. More Than Just Lift Walls: It’s a common misconception that shear walls must be around lifts. In reality, shear walls can be necessary even without lift shafts to effectively resist lateral forces. Deflection Control: Shear walls help control story drift and deflection, allowing for smaller column sizes and more efficient designs. 💡 Advice: Understanding the true function and behavior of shear walls is essential for effective structural design. Are you confident in your knowledge about shear walls? 👉 Read the full blog post to verify your facts - https://lnkd.in/gc7X7z8D #StructuralEngineering #CivilEngineering #ShearWalls #ConstructionSafety

BUILDING BLOCKS OF STABILITY: EXPLORING THE TYPES OF STRUCTURAL SUPPORTS AND CONNECTIONS The phrases "support" and "connection" in structural engineering and construction relate to various methods of stabilizing and joining structural parts together. Comprehending these kinds is essential to creating secure and functional constructions. The loading of structural systems is transmitted to the ground by a number of mechanisms. Every connection is made to be able to transfer or support particular types of loads or loading circumstance. Understanding the forces that can be transferred and resisted at each level of support throughout a structure is a prerequisite for conducting a thorough analysis of it. The real actions of a connection or support can be highly intricate. However, the parts that comprise each structural system behave differently depending on the conditions at each support. SUPPORT TYPES ROLLER SUPPORTS The roller supports have unrestricted rotation and translation along the surface they rest on. The surface can have any angle of slope, be vertical, or be horizontal. A single force that is perpendicular to and away from the surface always results as the reaction force. On lengthy bridges, roller supports are typically found at one end. This enables the bridge's construction to flex and expand in response to temperature variations. The bridge construction might be "locked" in place, allowing the expansion pressures to crack the supports at the banks. Additional options for roller support include a system of gears, rockers, or rubber bearings with restricted lateral movement. PINNED SUPPORTS Though not a moment, a pinned support can withstand forces that are both vertical and horizontal. They will permit rotation but not translation of the structural member in either direction. In actuality, some connections may resist a tiny amount of moment, but many connections are presumed to be pinned connections. It's also possible for a pinned connection to just permit one direction of rotation, preventing rotation in any other direction. An idealized knee would be a joint that resists lateral movement and only permits rotation in one direction. FIXED SUPPORTS A moment, as well as horizontal and vertical forces, can be resisted by fixed supports. They are also referred to as stiff supports since they impose restrictions on both translation and rotation. This implies that a structure can be considered stable with just one fixed support. It is possible to satisfy all three equilibrium equations. An excellent illustration of this type of support is a flagpole embedded in a concrete foundation. A moment and two forces—horizontal and vertical—are always included in the representation of fixed supports.

Staggering of rebar lap, In Eurocode 2 (EC2), which is the European standard for the design of concrete structures, staggering of lap splices is recommended to ensure a more uniform distribution of stress and to avoid potential weak points in the structure. Here are the main reasons why staggering lap splices is important: 1.Improved Structural Integrity 2. Stress Distribution 3. Reduced Congestion 4. Ease of Construction
