Everything about Civil Engineering
Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. Typically, estimation involves “using the value of a statistic […]
RCC RETAINING WALL(CANTILEVERTYPE) MAX 6.0 MTR HEIGHT INCL COLUMN LOAD IN LINE Retaining walls are used in the construction of basement below ground level, wing walls of bridge and to retain slopes in hilly terrain roads. Retaining wall can be constructed with masonry as well as reinforced concrete. In case of masonry retaining wall, the […]
Reinforced Concrete Staircase Reinforced concrete is perhaps the most suitable of all the said materials for the construction of stairs. The various advantages of reinforced concrete stairs are given below They have requisite fire resisting qualities to a great extent They are durable strong pleasing in appearance and can be They are durable, strong, pleasing […]
The main function of the trusses is to support roof, strengthen bridges, or support towers. They are developed for sustaining loads. Generally they are built with long, straight members associated with joints at the end of each member. Jeff Hanson shows the method of joints system in order how to discover a zero force member for […]
The use of reinforced concrete with steel rebar is increased after the invasion of environment factors on the constructions (Why Plastic Elements are used in Concrete Cover?). There is a need for concrete cover between the distance of the surface of concrete to the first level of bar. That is called Armator and is main parameter […]
Metal roof trusses, just like wood trusses, have their advantages and disadvantages. Some builders prefer to the metal roof truss because the building of a structure is all about precision and metal has a more precise measurement than wood. Safety is also an issue when deciding to use a metal roof truss or a wood […]
Detail of Roof Trust Roof Design The roof design and roofing materials have a significant impact on the finished appearance of the residence. Roof Slope Roof slope is the slant of the roof. Shown on a drawing as a slope ratio diagram or fractional pitch. The slope diagram represents the ratio between the rise and […]
One Way Slab One way slab is supported by beams in only 2 sides. 2) The ratio of longer span panel (L) to shorter span panel (B) is equal. or greater than 2. Thus, L/B >= 2. 3) Main reinforcement is provided in only one direction for one way slabs. Two Way Slab Two way […]
Rafters and trusses are not same and there are many differences between these two. As there are confusions on rafters and trusses, we decided to cover this topic in this post. Rafters The quality of Rafters is the same as the quality of Trusses unless you have decided to opt for an exposed rafter look, otherwise the results […]
Mix design is commonly referred by mix proportion in a selective zone where same materials are used in concrete. Suppose, in Bangladesh, most of the structural designers refer concrete mix design as ratio in drawing. Because materials of same properties are used in all over the Bangladesh. The question is, How do we estimate materials […]
