Wide-flange sections are manufactured in groups with a common set of inner rollers. Within each of these groups, the dimensions and properties are varied by increasing the overall depth of the section (thereby increasing the flange thickness) and then letting the web thickness increase as well.

Design for Torsion is moment act along the longitudinal axis of the beams, two types of torsion exist in structures first primary or equilibrium torsion as shown inFig. The torsion resistance is provided primarily by closed stirrups and longitudinal bars located near the surface of the member.

Shear reinforcement is designed to resist shear forces in excess of the shear strength of concrete. They are provided in forms of vertical or inclined stirrups or longitudinal reinforcement bent up at 45 degrees at locations where they are no longer needed to resist bending.

Generally, we calculate deflection by taking the double integral of the Bending Moment Equation means M(x) divided by the product of E and I (i.e. Young’s Modulus and Moment of Inertia). … This number defines the distance in which the beam can be deflected from its original position.

Introduction. Crack width calculation is one of the serviceability requirements in the structural concrete elements. … The crack width of a flexural member is obtained by multiplying the maximum crack spacing by the mean strain of the flexural steel reinforcement.

A corbel is a short cantilever projecting out from a column, a wall, or the side of a beam. A corbel is designed to support another member, usually a beam or girder, but may also be used to support a slab. ACI 318 restricts the term “corbel” to a member having span-to-depth ratio which is less

Flexural members are slender members that deform primarily by bending moments caused by concentrated couples or transverse forces. In modern construction, these members may be joists, beams, girders, spandrels, lintels, and other specially named elements. But their behavior in every case is essentially the same.

A reinforced-concrete beam having projecting ledges for receiving the ends of joists or the like. A beam is a structural element that primarily resists loads applied laterally to the beam’s axis (an element designed to carry primarily axial load would be a strut or column). Its mode of deflection is primarily by bending. The loads applied to the beam

Strength of the material considered under the shear failure, when a structure will fail is known as the design shear strength. The shear strength without any shear reinforcement relies on compressive concrete grade and percentage of tension steel in beam the modes of failure are described as follows, 1) web shear, 2) flexural tension shear and

Boundary conditions (b.c.) are constraints necessary for the solution of a boundary value problem. … Boundary value problems are extremely important as they model a vast amount of phenomena and applications, from solid mechanics to heat transfer, from fluid mechanics to acoustic diffusionA simply-supported beam (or a simple beam , for short), has the following boundary

UBs used in floors will support more force vertically than a standard square beam, but are weaker against horizontal movement and do not react well to twisting. They are used as a component in floor framing, and can be used with other beams and joists where extra load bearing capacity is required.

This publication provides guidance for vibration design of all steel-framed floor and building types. It deals with the human perception of vibration and the criteria by which it is measured. The concepts of floor response and the different types of excitation produced by occupant induced vibrations are explained. Simple design procedures are presented which show

A slab deck is one where the deck is analyzed as a plate. … A beam and slab deck is one where the beams may deflect somewhat independently, and any transverse forces are carried in the deck. A cellular deck is one where a number of thin slabs and webs will enclose cells within the deck.
