civil engineering-->> overview of arches

Arches An arch is an opening spanned by a collection of wedge shaped pieces ( voussoirs ) which stay in position by pressing in on one another. The joints between the pieces appear to radiate from some central point lying within the opening, and sometimes from points which lie outside, so every type of arch has a characteristic curvature. The simplest and visually most natural shape for an arch is the semicircle but many other designs have been used. How an Arch "Works" The central voussoir ( keystone ) is traditionally the last to be set into position to "lock" the whole thing into a strong and stable structure. A keystone is not always necessary, however; there may be a joint at the apex instead, as is common in Gothic arches. Gravity tries to pull the keystone downwards, but the thrust is carried on either side by the voussoirs immediately flanking it. These in turn have their total thrust carried through the whole semicircle of pieces in a sideways direc...

civil engineering-->>Types of arches

Types of arches With reference to the earlier post on arches, this one defines the various types of arches. Arches are constructed in four basic shapes that frame and support doors, windows, porches, and other wall openings: Flat arch Triangular arch Round arch Pointed arch Flat arch An arch having a horizontal intrados with voissoirs radiating from a centre below, often built with a slight camber to allow settling is called a flat or jack arch. French arch: A flat arch with voissoirs inclined to the same angle at each side of the center. The mortar joints do not, therefore, radiate to a common centre. Not, technically, a proper arch, and of weak form. Triangular arch It is a primitive form of arch consisting of two stones laid diagonally to support each other over an opening. Hence, the span is limited by the size of the available material. Corbel arch: A false arch formed by corbelling courses fro...

civil engineering-->>Determinacy, Indeterminacy and Stability of Frames

Determinacy, Indeterminacy and Stability of Frames : Structural engineers must be able to apply judgment rather than stated rules. The most important aspect of structural design is not the ability to apply formulas or manipulate mathematics. The most important skill for the structural engineer is to be able to stand back, look at a drawing or sketch and determine whether a structure is stable, and if it is stable, to be able to determine how it will carry the applied loads. For a very complicated structure this might be more difficult and a computer can provide some help, but ultimately it is the skill and concern of a good structural engineer which produces good structural designs which have integrity. Another important closely related skill is the ability to determine whether, and to what degree, a structure is statically indeterminate. There really aren’t many rules and rules may be difficult to apply in any case. For this reason, we need experience. A skilled structural...
