Concrete Stress–Strain Models for Cross-Section Design in EN 1992-1-1
Concrete is a nonlinear material, and its behavior under loading cannot be captured by a single universal stress–strain relationship. To account for different strength classes, loading conditions, and...
Design of One-way Post-tensioned slab – Worked Example
This article presents a detailed example of designing a one-way post-tensioned car parking structure. It addresses key considerations such as durability and cover requirements, gravity load calculations, prestress...
Durability of Concrete Structures
Durability is the ability of structures to meet the requirement of serviceability, strength and stability without excessive maintenance throughout its working life. The level of maintenance should not...
Creep Deformation in Concrete Structures
When a load is applied to a steel member it deforms gradually. The deformation increases proportionately to the increment in the applied load. If the load is not...
Design of Post-tensioned (PT) Slabs – an overview
Post tension concrete slabs are a type of prestressed concrete structure, wherein high-strength steel cables or wires are used to apply compressive force to concrete slabs before its...
Load Balancing Method for Post – tensioned Concrete Design
Load balancing is the concept of counteracting a portion or all of the external loads on a concrete member by placing the prestressed tendon along a determined curvature...
Design of PSC Beam for Shear Strength – Worked Example
This article presents a worked example on evaluating the shear strength of a prestressed concrete (PSC) beam using EN 1992-1-1-2004. The beam shown below is an I beam...
Design of Prestressed Concrete Beam for Flexural Capacity – Worked Example
This article presents a worked example on evaluating the bending capacity of a prestressed concrete beam. After verifying the stresses within a prestressed beam is within limit, it...
Constructing Magnel Diagram for prestressed Concrete beam – Worked Example
This article presents a worked example on the construction of magnel diagram for the design of a prestressed beam section. The beam that shall be designed is the...
Magnel Diagram for Prestressed Concrete Design.
This article explains the importance and application of magnel diagram in prestressed concrete design. Why Magnel Diagram? In a previous article on verification of stress in beams published...
Verification of Stress in a Prestressed Beam – Worked Example
This article shows a practical worked example on how to check the stress in a prestressed concrete beam using the combined stress approach. Verifying the stress will enable...
Design of Prestressed Concrete to Eurocode 2 – an Overview
Prestressed concrete as the name implies is a concrete that is subjected to prior compressive stresses before its working life. This technology is born out of the need...
Structural Design Philosophies
Amuletola Rasheed Prestressed Concrete Design, Reinforced Concrete Design, Structural Steel DesignPost read time 4 min read Designs are generally carried out under the guide of one philosophy or hybrid of philosophies; structural engineering field is no exception to this premise. In structural engineering over...
