🔩 Prying Effect in Base Plate Steel Connections 📚 The flexibility of the base plate can lead to deformations that increase the tension applied to the anchors. The base plate corners can become compressed against the concrete, inducing additional prying forces, which, in turn, lead to an increase in the tensile force in the anchors. 💡 A key factor influencing the magnitude of prying forces is the thickness of the base plate. A thicker base plate can significantly reduce the prying effect, contributing to a more efficient connection design. In the example 👇, the relationship between base plate thickness and the prying effect is graphically presented 📊. The prying factor is considered as the ratio of the total tensile forces in all anchors to the applied load. For selected thicknesses, the contact stress in the compressed base plate corners is also shown. #StructuralEngineering #SteelConnections #BasePlate #Anchor #Prying #DlubalSoftware #RFEM

Stirrups, or shear reinforcement, are essential for reinforced concrete beams and columns, improving their load capacity and structural integrity. They resist shear forces caused by lateral movement and prevent shear failure. ✔ Beams: 1️⃣ Shear Force Resistance: Stirrups counter shear forces that can cause diagonal cracking along the shear plane. 2️⃣ Concrete's Weakness in Tension: Stirrups prevent cracks from widening in areas under shear stress. 3️⃣ Ductility: They increase the beam's ability to deform without sudden failure. ✔ Columns: 1️⃣ Shear Resistance: Stirrups strengthen columns against shear forces from axial loads and bending moments. 2️⃣ Buckling Prevention: Stirrups confine the concrete core, enhancing stability. 3️⃣ Ductility: They improve energy dissipation, crucial during events like earthquakes. #mehrtashsoltani

Why you should avoid the 90° bending on stirrups and consider 135°. check for more structural significance of stirrups.

🏭 Reinforcement tensioning device: selection and use ⚙ The tensioning of reinforcement is an important process in production, ensuring the durability and strength of reinforced concrete structures. PAUL jacks are the leading rebar tensioning equipment due to their reliability and efficiency. 👉 https://lnkd.in/e2SdgF8g #pauljacks #tensioningintheprocess #steelstrandtensioningjackspaul #tensioningofreinforcement #tensioningdevice

Crank bars, also known as bent-up bars, are provided in slabs for the following reasons: 1. **Shear Resistance**: Crank bars help in resisting shear forces, especially near supports where shear forces are generally high. 2. **Distribution of Load**: They help in distributing the load more evenly across the slab, providing additional support where needed. 3. **Anchorage**: The bent-up portion of the bars provides better anchorage and bonding with the concrete, ensuring that the reinforcement stays in place and works effectively. 4. **Preventing Sagging**: Crank bars help in preventing sagging and deflection of the slab by providing additional support to the concrete. In summary, crank bars are essential for enhancing the structural integrity and load-bearing capacity of slabs in construction. Feel free to ask a question in relation for this...

As per your understanding, do you think that you have the right to install a "Post Installed Adhesive Anchor" to a concrete element before 21 days in case the concrete compressive strength reached a value higher than the one expected at the 21th day?! Example: F'c (21)=25 MPa and F'c (14)=27 MPa. #Anchorage_to_Concrete

Structural cracks are one of the concerning factor in retro-fitting project. It can be because of number of factors i.e., low strength of existing concrete, vibratory activities on weak structure, condition or aging of structure and many more. These cracks can vary from minor to major or through depending on severity & condition of structure. There are number of remedy but in this post i want to emphasize about epoxy injection treatment, Initially it is closed with help of packer & filling and epoxy is injected with high pressure, due to high viscosity of liquid & hardener it can spread and rest even in minor cracks. Also it goes in the pours of concrete, develop bond between with surface, once hardened it act as medium that binds both sides of crack. For through cracks it is recommended to inject from bottom of slab instead from above, at an angle of 45. So that we can have an enclosed system. #CivilEngineering #Retrofitting #Cracksremedy
