An engineer needs to carry this calculation out for every column and every floor, summing the results at the end to arrive at a cumulative load for a given column at the foundation.
Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed. … The program provides for the ultimate strength and service stress design and analysis of one-way beam and slab and two-way flat plate systems.

Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called ‘drop panels’

Ribbed slabs are slabs cast integrally with a series of closely spaced joists which in turn are supported by a set of beams. The main advantage of ribbed floors is the reduction in weight achieved by removing part of concrete below the neutral axis. … Solid slabs of uniform thickness can be one-way or two way.

A Ribbed Slab gives considerable extra strength in one direction while a waffle slab gives added strength in both directions. And this is possible only in monolithically cast concrete which is the two-way grid of beams. In comparison to the solid slab, the span limits of ribbed slabs are considerably longer.

The one-way slab is a slab, which is supported by parallel walls or beams, and whose length to breadth ratio is equal to or greater than two and it bends in only one direction (spanning direction) while it is transferring the loads to the two supporting walls or beams, because of its geometry.

SUBFRAME ANALYSIS The general steps for analysing a determinate frame are: Use equilibrium to find all reaction forces. Split the frame into separate members. Any point load or moment which acts directly on a joint between two or more members must be placed on only ONE of the members when they are split up.

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.

Punching shear is a phenomenon where a concentrated force on a slab causes a shear failure cone that “punches” through. Punching shear calculations require a demand value and a capacity value. Many hand calculations will consider a punching shear force against a punching shear capacity force.

Axial tension force can be defined as the force acting on a body in its axial direction. It’s a pulling force that will cause the body to elongate linearly in the positive direction causing a change in its dimension. Axial–Flexual Response of Cross-Sections The actual bending in a flexural member is about a single axis, defined earlier

The elements of design are the fundamental aspects of any visual design which include shape, color, space, form, line, value, and texture. Graphic designers use the elements of design to create an image that can convey a certain mood, draw the eye in a certain direction, or evoke a number of feelings.

Welded connections are connections whose components are joined together primarily by welds. Welds can be classified according to: … Positions of the welds: horizontal, vertical, overhead, and flat welds. • Types of joints: butt, lap, corner, edge, and tee.
Steel design, or more specifically, structural steel design, is an area of structural engineering used to design steel structures. In structural engineering, a structure is a body or combination of pieces of rigid bodies in space that form a fitness system for supporting loads and resisting moments. The effects of loads and moments on structures are determined through structural analysis.

The Segal Design Institute is an educational institute within the McCormick School of Engineering and Applied Science at Northwestern University. Segal is dedicated to the study of human-centered design at the undergraduate and graduate level.
Secondary Beam: A horizontal beam connecting primary beams (simply supported or shear connected.) Function: It will transfer the load to the primary beam and not directly connected to the columns

A girder is a large and deep type of beam that is used in construction. … A plate girder is typically an I-beam cross-section made up of separate structural steel plates which are welded, bolted or riveted together to form the deeper vertical web and narrower horizontal flanges of the beam.
The Design Manual is a document that is constantly being updated for various reasons. … This manual provides a convenient guide for NDDOT policies, procedures, and design values that are presently recommended for road and bridge designers.
