2.1.8.4.2. Splitting tensile strength: The splitting tests are well known as indirect tests used for determining the tensile strength of concrete. And sometimes it is referred to as split tensile strength of concrete. The split tensile strength is a more reliable technique to evaluate tensile strength of concrete (lower coefficient of variation) compared to other methods. The split tensile strength specimen of 150 mm diameter and 300 mm or 150 x150 mm cube specimen are placed between two plates with
Abstract: Beam deflections are important characteristics that can be shown by a loaded beam. Both cantilever beam and the simple beam were made of steel. The theory of deflection plays important roles in determination of modulus of elasticity because the relevant equations were applied in excel for purposes of getting the values. Engineers must understand beams from a theoretical perspective to enhance the safety of the designed structures. There are several aspects of the beams that were
A tall building or high-rise building is a building whose height creates different conditions in the design, construction and use than those that exist in common buildings of certain region and period[3]. The tallness of a building is a matter of a person’s or community’s circumstance and perception therefore, a measurable definition of a tall building cannot be universally applied. Tall building structures frame requires special structural arrangements, if they are subjected to appreciable lateral
Concrete is an extremely versatile and durable building material. Concrete can be used to build long lasting structures even in very harsh environments when it is made with adequate constituents and mix design and properly handled .performance problems that may arise occasionally are often due to the use of materials that do not full fill minimum quality requirements, unsatisfactory specifications or due to inappropriate construction methods. A concrete consists of sand, coarse aggregate

DEFLECTION Deflection is the distortion or movement of a structure and its elements, such as trusses and beams, from their original positions. It is as significant for a designer to regulate deflections and strains as it is to recognize the stresses due to loads. The practice of the ACI Code requirements, taking into account the non-linear relationship between stress and strain in concrete, has resulted in significantly smaller sections than those by the elastic theory. The ACI Code, also recognizes

Abstract – Concrete occupies unique position among the modern construction materials, Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance, known as a aggregate (usually made for different types of sand and gravel), that is bond by cement and water.Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weight to completely fill the form work and self consolidates without any mechanical vibration.
Emirates Steel’s biggest achievements could be summed up by saying that since its inception in 1998, the company has worked hard to produce the highest quality products for its consumers, thus establishing a strong brand name and position in the market. Emirates Steel has developed a brand strategy that revolves around clearly articulating its differentiation against competitors, and it continually push these differentiators to its customers by aligning its brand to its unique value proposition
How building codes have changed over the years A building code is a set of rules that specify minimum standards for constructed objects such as buildings and non-building structures. Building codes are generally applied by Architects, Engineers, Constructors, and Regulators. Building codes are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufactures of building products and materials, insurance companies, facility managers
and repeatable decision-making processes. Transferability is a negative because the study can be applicable to another group or another setting. Credibility is a negative because researchers might not have confidence behind the results of the study (Rebar & Gersch,
Published in 2008, the Building Information Modeling Protocol Exhibit by the American Institute of Architects was developed in order to establish guidelines on the use of BIM throughout a project. This is important in that it has addressed several outstanding questions such as, the responsibilities for each element of the model, the authorized uses for the model, the extent to which users can rely on the model, the management of the model, and who takes ownership of the model. After developing a
Around 3:00 pm on Sunday April 11, 1993 a riot started when prisoners returning from recreation time attacked prison guards in cell block L. The guards held the keys to the entire cell block and it did not take long for the prisoners to take full advantage of the keys. Four beaten guards were released within hours of the attack but 8 were retained. The riot was started for many reasons but the most obvious reason was TB testing on Muslims, they do not believe in using needles to take blood or for
Mathematics Education in America: A Troubled System in Need of Change On a trip to Fidler concrete in Goshen, Indiana, a man ordered forty feet of rebar for home use. When he went to pick up the rebar, the adult employee in charge asked the man what size pieces he would like. The man asked for six-foot sections. The employee furrowed his brow and said, “Now, if it were five foot sections, that would be ten of them for forty feet, right?” The man replied, “No, ten of the five footers would
The first time I experienced clay in depth was in my first ceramics class in college. This is where I spent hours of my time in the studio exploring. After my first soda firing, I knew that I wanted to start a career in clay. I am applying to the master’s program in ceramics to extend my knowledge of clay and to further develop my conceptual thought. Much of my time was spent in the studio during my time in college. My professor, Nick Roudebush, saw this drive and hired me as the head studio assistant
of the work done for buildings requires much more careful monitoring over an extended period of time. In addition, sometimes even concrete is not strong enough on its own. As a result, sometimes concrete must be installed with a particular gauge of rebar installed in various spots in order to reinforce the concrete. These specifications are very specific, and it is an exact science. A contractor must be aware of these things ahead of time, and must be sure that they have the personnel and the training
Part Three of the book “Just Like Us” written by Helen Thorpe is comprised of illegal undocumented individuals residing in Denver Colorado. The individuals consist of a group of four Mexican young adults all with the dream of one day attending college and finally obtaining a legal status within the United States. In this portion of the readings, Yadira, Marisela, Clara, and Elissa are entering their senior year at their University and have defined the odds of successfully completing college while
concrete, ready-mix concrete, reinforced concrete, terrazzo and Urbanite in details. In this introduction, we will briefly introduce the sub-topic or types of concrete. Reinforced concrete is stronger than basic concrete. Steel reinforcing bars known as rebar is incorporated in the concrete structure to act together in resisting the force. The steel reinforcing bars absorbs tensile and compression because plain conc... ... middle of paper ... ...sed concrete: a fundamental approach / Edward G. Nawy
Pillboxes were miniature forts or bunkers developed by the German army to give their trench lines extra strength in world war 1. Pillboxes are built in guard posts made out of concrete and they are most always equipped with loopholes through which the soldiers inside are able to fire small arms weapons. The very first name for pillboxes came from their similarity to the cylindrical and hexagonal boxes in which medical pills were sold before world war 1. They were also an effective tactic in trench
construction began in August of 2010 and the architect that was in charge of it was Rob Wellington Quigley of the FAIA Tucker Sadler & Associates. The main materials used when building it was concrete and all of the columns where supported with steel rebar, which is a piece of metal used to reinforce concrete. The dome was made out of eight steel ribs and eight steel-mesh sail as stated in the “Construction facts of the San Diego Central Library“. The main function of this building as its name says,
