In order to verify the results from the studies and testing’s that have been carried theoretical analysis is done via calculations to compare the answers. The numerical analysis that was carried out followed guidelines set by American Concrete Institute Committee (ACI Committee), their report entitled ‘Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures’ produced the guidelines and equations that each of the studies previously mentioned followed.
In this report analysis of external FRP wrap can be broken into two separate categories; strength and strain.
When calculating the compressive strength and strain in a member 5 main equations are used:
The ultimate strain of confined concrete is defined as:
ε_fe=0.0119-0.0205ρ_f

In order to predict the peak strength of concrete with external FRP of different unconfined strengths Riad Benzaid and Habib-Abdelhak Mesbah propose an equation based on the results that were obtained in Table 4.4. Figure 4.8 displays the interaction between fl,eff /f’co and f’cc/f’co. It can be observed that the strength ratio is proportionate to the volumetric ratio and the effective lateral confining pressure of the FRP is inversely proportionate to the unconfined concrete strength. Hence a linear graph is produced. Figure 4.8 Strengthing Ratio Vs Actual Confinement
The following equation can be used to establish the trend line:
〖f'〗_cc/〖f'〗_co =1+2.20 f_(l,eff)/〖f'〗_co
Equation 9
Where;
f’cc = the compressive strength of the confined concrete; f’co = the compressive strength of the unconfined concrete; fl,eff = effective maximum lateral confining

In Colonial Williamsburg there are many significant architectures. Buildings such as the Bruton Parish Church, Governor’s Palace, the Capitol, and the Magazine all had a big contribution in Virginia's history. Each building deserves a commemorative coin, but only one can be selected. By studying all the four structures, the one most deserving of a commemorative coin is the Magazine. During the Colonial times, the Magazine had many significant effects.
Chip sealing or bituminous surface is a normally used process globally for metalled road a roadway. A chip seal embody of a layer of asphalt binder that is superimposed by a layer of assemblage embedded in the binder. It endow aegis to the current stratum layer from tire disservice and a skid obstruction surface texture for vehicles. Chip sealing is ponder a low cost alternative weigh to variant asphalt surfaces and so far as several transit agencies have narrow budgets, its uses is probable to maximize in the future. The government of Madhya Pradesh manage an identical amount of chip sealed roads in lane kilometres.
In the next two paragraphs, I will show you the relationship
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.

center-to-center. The first confinement hoop set for the testing region, Hcr, was spaced at 1.125 in. from the center (i.e., mid-height) of the confined concrete column corresponding to a center-to-center spacing, s, of 2.25 in. between the confinement hoop sets in the testing region. A total of 10 confinement hoop sets were used in the testing region.

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.

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.
Predict/ roughly determine the Vmax and ½ Vmax values from the peak of the graph, where the slope of the graph levels off (the asymptotical line). Predict/ roughly determine the Km by reading off of the graph the corresponding substrate concentration on the x-axis for the ½ Vmax value. Plot a Lineweaver-Burke graph (the inverse of the velocity of the reaction vs. the inverse of the substrate concentration). Calculate accurate Vmax and Km values using the following equation for the Lineweaver-Burk
Fix or replace damaged tissue; biology has always been the main concern for scientists. Today, the most important instrument for tissue engineering scientists to produce replacement tissues and implants to repair or replace damaged tissue. Tissue engineering is generating a new field of study in which the principles of engineering and biology to correct the damaged tissue, uses and can renewal, operation and maintenance of tissue healing. In order to use an ideal scaffold Tissue engineering should have features such as non-toxic Cell and tissue properties to be fit.
Cracks 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
