bridges, roads, mining, and mills. Two other buildings are the Colosseum and the Pantheon. Materials The Romans mostly used brick, stone, cement concrete and/or marble. The Romans discovered that substituting the sand in concrete with volcanic ash would make a very strong cement. The Romans also debris, broken pottery and lighter materials into concrete and mortar. They also used wood,ceramics metal, and mudstone. Aqueducts Rome had 11 different aqueducts. They were between 10-100 km long…

TASK 4(P4):- Discuss the effect of loading structural material 1) You need to discuss the effect of compressive force, tensile force, shear force, bending force on structural member 1) Timber: Compressive force on timber: - The effect of a compressive force on a timber is a change in structure of a material and to carry a load within its limits. Tensile force on timber: - The tensile force is the pulling force exerted on both the ends of a timber. Both the ends of a timber will undergo tension…

Abstract Cold-formed steel section (CFSS) is a civil engineering material that still and always in ongoing research for utilising in building or construction works. The advantage of the CFSS is becoming so interesting in selecting it as a roof truss system and purlins. For having the roof truss system with stable and safe condition, the study of the truss member is carried out by using the cut-curving channel section. Before the cold-formed steel section has been curved, the process of curving…

There are several roof designs, depending on the shape and number of pitches. There is a flat roof, mono-pitched roof, pent roof, multi-pitched roof, A-frame, Asian traditional style, half-hipped, Karahafu, pyramidal and many others. Some of the designs are employed in specific regions and only when building codes allow it. But among the most popularly used roof style is a dual pitched roof. What is a dual pitched roof, you ask? It is a gable roof that features two slopes that meet at a central…

The Hōryū-ji Temple remain located in Nara prefecture Japan, is the oldest existing timber structure; dated from 607 AD. The temple’s construction is held up by structural elements called the Dougong, which are placed on top of large, firm and stable vertical pillars, to support the weight of upper stories, roofs and eaves. The Dougong is composed of overlapping wooden brackets; the ‘Dou’: a block placed on a column, creating space for multiple bow-shaped arms; ‘gong’, to be interlocked, which…

and covering the surface with cement. Our first job was to shovel several tons of gravel and rock into the new church. When our team arrived at the village for the very first time, there were two structures that stood out. The first was the fully concrete church that the villagers had spent close to a decade building. With its smooth walls and roof, it stood in stark contrast with their current building, which was nothing more than a few sturdy logs and…

For our design we have decided to do a bowstring bridge. A bowstring bridge normally are used to carry road and rail traffic. By bowstring bridges being able to use arches it makes it so that the weight of anything crossing the bridge is actually able to go straight down into the bridge instead of dispersing across the entire bridge. This makes sure that the bridge doesn’t have one spot taking on too much weight on the bridge. Bowstring bridges tend to be become stronger over time because the…
