ANALYSIS OF BRIDGE MODEL
STAAD Pro model of concrete bridge is created and analyzed for several loading position and the bridge is designed for critical loading condition. After completing the simulation analysis a prototype model is designed. Fig 1: STAAD Pro Model Fig 2: Loading on Model
III. DEVELOPMENT OF SIMILITUDE MODEL
Length Scale Factor (SL) = LP/LM is calculated and this length scale factor is used to get the similitude dimensions. The bending scale factor is calculated using the relation moment in Prototype /Moment in model. This Scale Factor is applied to the real time bridges which having the same geometry and loading conditions. Fig 3: Model Detailing
The prototype model of concrete bridge cast for the critical load obtained. A single pier with beam deck of the bridge is designed. Three numbers of samples were cast and are kept in curing tank. The model is to be tested for deflection, stress and strain.

I am making this appeal in response to the sanction that is imposed on me in reference to the case #3788. The hearing panel found me guilty on the charge of complicity in the course of construction scheduling COSC 603:299 and awarded me a grade of F* in the course COSC 603:699 Construction Scheduling for which I was enrolled in Spring 2015 semester. The basis of my appeal is that the sanction on me is not commensurate to the violation. I would like to provide the following rationale for my defense.
"An Occurrence at Owl Creek Bridge", is by Ambrose Bierce. The story tells of a Southern farmer, named Peyton Fahrquhar, who went to go disrupt the north’s railroad, which was a trap, and was caught and sentenced to be hung. He thought he had escaped death, but he was dying. This shows that time is very fluid. Sometimes what could be minutes may feel like hours or vice versa, and everyone experiences time differently.
Rome had lasted many years and provided many advances during that era, some of which were lost for centuries. Two important developments that Rome had made were concrete and the arch. Antony Kamm defined concrete on his website The Romans under the Art section as a mixture of clay and limestone heated to high temperature, then pulverized to powder at which mixed with water and sets as hard as rock. He later states that because of this invention, Rome was able to indulge their architectural ambitions. It is important to note that the Romans did not invent the arch, Kamm stats that “their development of it allowed them to exploit their penchant for resolving improbable situations”.
A brutal crash between a white 2002 Chevrolet Camaro Z28 and a city truck on Foster Road, San Angelo, Texas, caused severe injuries for two people, according to a statement released by the San Angelo Police Department. According to San Angelo police, at approximately 3:30 p.m. Tuesday, police and San Angelo Fire Department personnel were dispatched to the 5300 block of Foster Road for a major two-vehicle crash with entrapment. The driver of the Z28 Camaro, McKenna Bowie, 18, and the 16 year-old passenger had to be cut from the wreckage.
The Seafarers Bridge has no torsion stress and its stress is unknown. Its cantilever is its deck and it has symmetry in all the parts of the bridge. Its usurper is very solid in a way that it won’t move an inch. The size of The Seafarers Bridge is very reasonable for the locals. Reasonable because the bridge is not too small to where only one person at a time can go.
Assignment 2 CVE80006 Infrastructure Deterioration Modelling Concrete Crack Diagnosis Assignment The phenomenon of cracking in concrete may depend on several factors such as the amount of loading, rate of bleeding, amount of stress and strain generated in concrete, the composition of concrete and method of fabrication. The cracking of concrete has become severe due to advance construction process which demands high strength structure requiring an increase in stress, strain, and deflection resistance. The cracks in concrete are mainly classified as structural crack and non-structural crack.
Notwithstanding the magnitude of the project and the technology available at the time, the building system adopted was designed specifically for the construction of a bridge. Caisson technology was used in order to dig the foundations of the bridge. Labourers excavated the riverbed in watertight retaining wood structures called caissons which were dropped into the river. Granite blocks pinned these wooden boxes down to the river floor. Compressed air was pumped into these chambers in order to keep the water and debris out.
Reaction to “An Occurrence at Owl Creek Bridge” by Ambrose Bierce While reading this story I found to focus on the element of theme because the story was a bit unusual. The author explores the idea of time in this story because there are specific parts when situations are happening and the time comes off as “quickly”, and it seems that in other moments, time moves in slow motion. An example would be when the main character is tied up and is facing the military.
Compare the Burj Khalifa and the Willis (Sears) Towers: key facts, construction, height, technical details. The buildings in our lives are improving very fast and some of these buildings are towers and skyscrapers. Willis Tower and Burj Khalifa are two of the most amazing skyscrapers on the planet. Both have their own characteristics in construction, design and technical features. This essay will compare between Burj Khalifa and Willis Tower in terms of facts, design, construction and technical features.
I had first formal exposure to civil engineering in course “Architecture 1”. This course provided me the fundamental concepts of civil architectural principles such as designing procedure, architectural component’s layouts, functional spaces as well as environmental impacts. To strengthen my concepts I pursued the courses “Strength of Materials”, “Structural Mechanics” which gave me essential knowledge about the external and internal forces occuring in simple structural elements under action of various types of loading as well as fundamental concepts in structural analysis such as modellisation, classification of structures. I gained valuable exposure to the analysis of simple structures submitted to compound loadings by the application of the principle of superposition for such cases as: unsymmetric bending, combined bending and tension or compression, combined bending and torsion, general compound loading. Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures.
In this article, Linkin addresses the narrative techniques used by Bierce in An Occurrence at Owl Creek Bridge. The argument presented is that Bierce “deliberately discloses his readers to affect a mimetic correspondence between the audience’s perception of the text” (137). Linkin reveals that shifting points of view during the story allow the readers to believe what is being said by the character Peyton Farquhar is taking place at the moment he is speaking. These techniques also manipulate how much time has elapsed while Peyton speaks. Linkin does a decent job of arguing her point.
Introduction: The term 'advanced development technology ' in construction industry covers an extensive variety of present day techniques and practices that envelop the most recent improvements in materials technology, design methodology, amount studying, offices management, administrations, structural examination and design, and management skills used in construction industry. Technological advancements in different fields such as medical industry, business industry, electrical engineering, mechanical engineering, civil engineering etc. have brought many positive impacts. Fusing advanced development technology into construction industry can expand levels of value, proficiency, safety, maintainability and incentive for money. The advanced technologies in construction industry are very useful for all type of small and large scale construction projects.
Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.

An introduction to highway building: Although there are many methods to constructing a road, all are based on the principle that geographical objects are removed and replaced with harder and more wear-resistant materials. The pre-existing rock and earth is removed by digging or explosions. Tunnels, embankments and bridge are then added when necessary. The material that the road is being constructed from is then laid by various pieces of equipment, which will be looked at in greater detail in this assignment. The construction management of roads has become increasingly more difficult as larger structures are constantly being required in increasingly short amounts of time.
