High Strength Materials Essay
General advantages of use of high strength materials –
Due to the use of the high strength materials size or dimensions of structural members are reduced, which may increase the clearances or reduce storey heights.
High strength materials permit the use of large spans (greater than 30 m) with shallow members, even when heavy load are encountered.
In addition to general advantages, such as excellent fire resistance of high strength concrete, low maintenance costs, elegance, high corrosion-resistance of high strength steel, adaptability etc, the structure is found to sustain the effects of impact or shock and vibrations due to the use of high strength materials.
Cost saving in foundation and supporting members is possible as smaller loads applied due to the smaller dimensions are used.
Smaller deflections are caused

Low rate of maintenance and repairs – High strength concrete increases the life of structure with low rate of maintenance and repairs as it provides high durability even at conventional joints which are often the weakest links of the structures.
7. Helps in increasing span using less beams – High strength concrete provides higher shear resistance and flexural strength as compared to normal strength concrete due to high strength concrete can be used to increase the span of beams with less intermediate beams.
Advantages of use of high strength steel:
1. High strength - The tensile strength of pre-stressing steel is given in terms of the characteristic tensile strength (fpk).
Nominal Diameter 2.5 3.0 4.0 5.0 7.0 8.0
Minimum Tensile Strength (fpk) N/mm2 2010 1865 1715 1570 1470 1375
Strength of high strength steel is much more than normal steel.
2. Adequate ductility
3. Bendability – High strength steel has high bendability that is high strength steel can be bend easily which is required at the harping points and near the anchorage.
4. High bond – High strength steel provides very good bond with concrete which is main requirement of pre-stressed
B1 Unit 1 Assignment
481 Words | 2 PagesB1: Whilst working as piping technical authority in current role (Year 2013), for Shell Canada Piping class development, I had established flange joint integrity calculation procedure for the usage of full rating for intermediate strength bolts in piping classes. I have utilized this opportunity within my own responsibility to ensure the mechanical integrity. I had carried out desk top study based upon ASME SEC VIII, Appendix-2 & ASME PCC-1 for verifying the integrity of flanged joints. This study has concluded that, usage of intermediate strength bolts need not to restrict the full rating of flange joints.
Pros And Cons Of Truss Bridge
754 Words | 4 PagesThe interior diagonals are under tension under balanced loading and vertical elements under compression. If pure tension elements are used in the diagonals then crossing elements may be needed near the center to accept concentrated live loads as they traverse the span. It can be subdivided, creating Y- and K-shaped patterns. The Pratt truss is practical for use with spans up to 250 feet (76 m) and was a common configuration for railroad bridges as truss bridges moved from wood to metal. They are statically denominate bridges, which lend themselves well to long spans.

Pros And Cons Of Mil Mill Construction
646 Words | 3 PagesWhereas the floor collapse will and should prevent any further interior operations in the building, the exterior of the building should remain stable prevent a complete structural collapse that would endanger other buildings and anyone located in the immediate collapse zone. Mill construction also incorporates scuppers in the building to drain excess water from the building. These play a key role in alleviating excessive weight caused by fire operations that if allowed to build up on the floors could cause a
Welding Essay
381 Words | 2 PagesWelding is a great job but not many people know what welding is or how it work. According to Thomas net welding is the process of joining metal together with heat welders can work on many kind of structures such as mobile homes, pipes, steel reinforcement and others. Because welding is a relatively easy manufacturing process and provide a great deal of strength (Thomas).To become a welder you need four skills the first skill you need is problem solving because welder must be exceptional problem solver who pay attention to details. They have to spot flaws in materials and designs troubleshoot broken areas and know to fix parts or equipment. The second skill math and science welders constantly use their knowledge of fundamental science and math

765 Words | 4 PagesSteel is durable because it lasts for a long time so you do not have to worry about it rusting. Steel is also strong because it can hold a lot of weight. Because of the durability and strongness of steel the invention of skyscrapers were starting to appear. Steel is strong enough to be used for building structures and big projects. Although steel was used with big tasks it is also used in small items that people use in their everyday life.
Lego Personal Statement
1451 Words | 6 PagesI 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.

Tension Test Lab Report
1182 Words | 5 PagesTable 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.

2638 Words | 11 PagesCracks are expected at intervals in this slab (Usually .90 to 1.2m) and are held together with structural steel. Appropriate spacing between cracks must be determined in order for this method to work. Continuously reinforced roads can sometimes be more expensive than the other two methods due to the higher quality of steel used in its construction, however this can be lowered by the reduced amount of cement used in the concrete mixture due to the thinner layer of concrete in comparison with the other two methods. With proper management, this method can be similar to the other two in terms of durability and cost
