Similar construction with earthfast posts is called stolpteknik. and Palisade construction where many vertical wall timbers or planks have their feet buried in the ground called post in ground or earthfast construction is called palissadteknik. (see also Palisade church) Swedish plank-frame construction is called skiftesverk. This is a ...
Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.
Live Geometry is a free CodePlex project that lets you create interactive ruler and compass constructions and experiment with them. It is written in Silverlight 4 and C# 4.0 (Visual Studio 2010). The core engine is a flexible and extensible framework that allows easy addition of new figure types and features.
Crown – A post on a tie beam or collar beam carrying a crown plate. [26] Crown strut: A piece similar to a crown post but not carrying a plate. [27] Ashlar – or ashlar piece: Short post from a tie beam to a rafter near a masonry wall. [28] Purlin – A post supporting a purlin plate, may be plumb or leaning (canted).
A stiffer beam (high modulus of elasticity and/or one of higher second moment of area) creates less deflection. Mathematical methods for determining the beam forces (internal forces of the beam and the forces that are imposed on the beam support) include the "moment distribution method", the force or flexibility method and the direct stiffness ...
Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
Pole building design was pioneered in the 1930s in the United States originally using utility poles for horse barns and agricultural buildings. The depressed value of agricultural products in the 1920s, and 1930s and the emergence of large, corporate farming in the 1930s, created a demand for larger, cheaper agricultural buildings. [2]
If there are mixed with distributed loads and concentrated, the moment diagram (M/EI) will results parabolic curves, cubic, etc. Then, assume and draw the deflection shape of the structure by looking at M/EI diagram. Find the rotations, change of slopes and deflections of the structure by using the geometric mathematics.
