Lateral Torsional Buckling occurs in unrestrained beams. A beam is unrestrained when its compression flange is free to displace laterally and rotate. When I sections are used as beams or beam columns the compression flange is under compressive stress and has a tendency to buckle but it is attached to the tension flange which resists … Read more Lateral Torsional Buckling | Factors influencing LTB
Precast Concrete and Factory Production The corporate goal behind the use of a production method that is to establish itself in the marketplace must be: to produce a product better or cheaper or faster than the competition. So what is the situation with construction using precast concrete elements? Improved quality Production in an indoor environment … Read more Advantages of Precast Concrete and Factory Production | Quality | Cost | Time
Preloaded Bolt Bolts are tightened such that a high tension, usually above yield strength, is developed in the bolts, these are called preloaded bolts. The plates of the connection are thus clamped together and shear transfer between the plates is achieved through friction. Preload is the tension load developed in a fastener while tightening. The … Read more Preloaded Bolts (Pre-tensioned Bolts) | Advantages | Applications
Formwork The function of formwork (Shuttering) is to hold freshly placed and compacted concrete till it has gained sufficient strength to be self-supporting. It also serves the purpose to produce a concrete member of the required shape, size and the desired finish. 6 Major Design and Construction requirements of Formwork The formwork should be sufficiently … Read more 6 Crucial Design & Construction Requirements of Formwork (Shuttering)
Precast beams with straight, fully bonded tendons are very convenient for detailing and manufacture. However, one of the advantages of prestressing, namely using the dead toad of the unit to reduce transfer tensile stresses in the concrete, is lost in such members, because this tension becomes most critical at the ends of the beams, where … Read more Stress Control by Deflecting & Debonding Tendons in PSC Design
Civil Engineering is the oldest and quintessential engineering profession. It encompasses a variety of sub-disciplines and jobs. Civil engineering is the oldest branch of engineering which is growing right from the stone age civilization. American Society of Civil Engineering defines Civil Engineering as the profession in which a knowledge of the mathematical and physical sciences … Read more Civil Engineering
