Choose Affordable Colorbond Carports Wisely A structure which is partially covered and can offer limited protection to vehicles from harsh weather conditions is known as a carport. This can be fixed to a wall or even be free standing. This carport has either one wall or two, and not covered on all four sides like other structures. Though this offers less protection as compared to garages, you can get good amount of ventilation from your vehicles with them. An ‘enclosed’ or a ‘Mobil’ carport is…

Sheet Metal Roofing If you are in the midst of planning your next new home construction or roof replacement project, you may have come across sheet metal roofing in your research. To most homeowners who do not live in major urban centers, the idea of sheet metal roofing on a residential home may seem foreign. However, sheet metal roofing is experiencing a real moment in the residential home construction world. Sheet metal roofing is exactly what it sounds like: it is a roof made-up of…

Bridge Design: Edmond Liu My popsicle bridge is based on a truss design, which is a bridge design held up by a connected structure composed of many smaller pieces. In particular, my bridge is a variation of the Queen Post Truss Bridge, which has two central supporting posts to allow for a greater span allowing for larger contact points.

increase in the stress. Such behavior is directly related to the confinement effectiveness by CFRP layers and hoops reinforcement, which decreases with an increase in the geometric dimensions of concrete column. The resulted behavior is believed to be much degraded beyond the peak point due to dilation in concrete when using inadequate amount of confinement material (Harries and Kharel 2003). After the peak load was reached, the decrease in axial strength was more remarkable for larger…

The development in the construction industry has made engineers, architects and designers very creative and ambitious in building projects. The designs are becoming innovative and attractive. To achieve this, tremendous amount of weight placed was on materials leading to their inability to bear this significant weight. Consequently, to be able to achieve the structural design and strength engineers developed the truss. Trusses are web-shaped structures that are able to bear tremendous weight.…

A concrete patio or entryway is a standard on most homes in Texas. Owners don’t typically even acknowledge that they can transform this feature of their home although it’s typically the first thing a visitor sees. A concrete overlay is a cost efficient way to add style and a modern touch to the front of a home to boost its curb appeal. A concrete overlay is an ideal way to transform any concrete feature that needs a little style. A front porch or entryway is typically just plain concrete with a…

Design and implementation of an Electronic system for identification of rebars in reinforced concrete. Abstract- In this paper non-destructive method is implemented in which magnetic self-designed sensor is used to detect position of rebar in reinforced concrete. During the renovation of old buildings it is necessary to locate rebar accurately to avoid damages in construction. This is achieved by Magnetic sensor which is made up of E-shaped core also primary and secondary windings. Due to…

usually fibrous but may have a particulate or other shape (web.mit.edu). They are produced when two or more materials or phases are used together to give a combination of properties that cannot be attained otherwise. For example steel reinforced concrete, plywood and fibre glass. 1.2 What is a Ceramic Matrix Composite (CMC)? CMCs are a subgroup of composite materials. They consist of ceramic fibres embedded in a ceramic matrix, thus forming a ceramic fibre reinforced ceramic (CFRC) material. 1.2…

\par Magnesium: As aluminum has been established as a leading role in automotive industry, the use of magnesium in automobile applications is yet limited. Magnesium exhibits a poor formability whereas aluminum has superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic…

pre-cast concrete components such as stairways, beams, floors and walls. These elements lend structural integrity, fire safety and insulation benefits. For companies that transport these heavy construction materials, great care must be taken to ensure they arrive at their destination in a timely, safe, and efficient manner. Weight Limits While flatbed trailers are the standard mode of transportation for heavy construction materials, they are not all capable of handling some pre-cast concrete…
