Rubble arches are very weak and used only for inferior work. Types of Arches based on Workmanship and Construction Materialsīased on material used for construction and workmanship, arches may be classified as:īased on workmanship, these are sub divided into two types. Tudor arch is also having four centers.Ī good semi-elliptical shape arch contains five centers. Venetian arch is a typical example for four-centered arch. Semi elliptical and Florentine arches are generally having three number of centers Pointed or gothic or lancet arches are generally come under this type.
In some cases, perfectly circular arch is provided for circular windows which is called as bull’s eye arch is also come under these category. Segmental, semi-circular, flat, horse-shoe arches and stilted arches are one centered arches. Types of Arches based on number of Centersīased on number of centers the arches are classified as: This is a type of arch of semi-ellipse shape and having three or five Centers. The Centre of arch lies on the horizontal line through the tops of vertical portions. Stilted Arch consists of a semi-circular arch with two vertical portions at the springing’s. The ends of this arch should be carried sufficiently into the abutments.
In case of relieving arch, we can replace the decayed wooden lintel easily without disturbing the stability of structure. Relieving arch is constructed above flat arch or on a wooden lintel to provide greater strength. It has three Centre’s, all located on the springing line. Intrados of arch is in the shape of semi-circle and rest of the arch is similar to Venetian arch. It contains four Centre’s, all located on the springing line. Venetian arch is also pointed arch but its crown is deeper than springing’s. This may be either isosceles or equilateral. In this type of arch two arcs of circles are met at the apex hence triangle is formed. The other name of pointed arch is Gothic arch. This is generally considered for architectural provisions. Horse Shoe Arch is in the shape of horse shoe which curves more than semi-circle. In this type of arch, the Centre lies exactly on the springing line. The shape of arch curve looks like semi-circle and the thrust transferred to the abutments is perfectly vertical direction since skewback is horizontal.
Types of Arches based on Workmanship and Construction Materialsīased on the shape of construction arches are classified into 10 types and they are discussed below.Types of Arches based on number of Centers.
