This document discusses engineered rebar made of MST-BAR for concrete structures as an alternative to traditional steel rebar. It outlines the problems with corrosion of steel rebar over time and lists typical examples. MST-BAR is made of glass fiber reinforced polymer (GFRP) and has higher tensile strength, is lighter weight, and is completely resistant to corrosion compared to steel. The document provides test results and charts comparing the mechanical properties of MST-BAR and steel. It lists the main advantages of MST-BAR and outlines typical applications, approvals, codes, and standards. Cost analyses show that MST-BAR provides major long-term savings due to its 100-year lifespan compared to 25 years for steel
Stress ribbon bridges are tension structures similar to suspension bridges. They transmit loads via tension in the deck to anchored abutments. Unlike simple spans, the ribbon is stressed in compression, adding stiffness. The first was built in Switzerland in the 1960s. They consist of precast concrete planks supported by bearing tendons and separate prestressing tendons to create the catenary shape. Stress ribbon bridges are economical, aesthetic, and require minimal maintenance.

GFRP rebar offers benefits over steel rebar such as corrosion resistance, higher tensile strength, lower weight, and a projected service life over 100 years. NuStar plans to use pultrusion, an established manufacturing method, to produce the GFRP rebar in various diameters and shapes at competitive linear foot prices. Facility requirements, management plans, and production projections are also outlined.

Bridge bearings allow movement of the bridge superstructure and transfer forces between the superstructure and substructure. Common early bearing types included pin, roller, rocker, and sliding metal bearings. Modern bearing types include pot, elastomeric, laminated elastomeric, and sliding bearings. Selection of the appropriate bearing type depends on required movements and load resistance based on AASHTO guidelines. An example is provided demonstrating the design process for an elastomeric bearing, including calculation of bearing loads, preliminary sizing, and stress checks to determine the final design thickness.

The document discusses corrosion in steel reinforcement in concrete. It describes the mechanism of corrosion as an electrochemical process where rust forms. The main causes of corrosion are cracks in concrete, moisture, permeability of concrete, carbonation, chlorides, sulphate attack, and alkali-aggregate reaction. Some preventive measures include avoiding congested reinforcement, using impermeable concrete, maintaining proper cover over reinforcement, and applying protective coatings. Factors like water-cement ratio, permeability, and cracks can affect the rate of corrosion.

Suspension bridges are suspended from cables. The earliest suspension bridges were made of ropes or vines covered with pieces of bamboo. In modern bridges, the cables hang from towers that are attached to caissons or cofferdams. The caissons or cofferdams are implanted deep into the bed of the lake, river or sea. Sub-types include the simple suspension bridge, the stressed ribbon bridge, the underspanned suspension bridge, the suspended-deck suspension bridge, and the self-anchored suspension bridge. There is also what is sometimes called a "semi-suspension" bridge, of which the Ferry Bridge in Burton-upon-Trent is the only one of its kind in Europe.[19]
The longest suspension bridge in the world is the 3,909 m (12,825 ft) Akashi Kaikyō Bridge in Japan.

Pt slab design philosophy with slides and pictures showing benefitPerwez Ahmad
This document summarizes the history and development of post-tensioned flat slab construction. It began with early research and development of prestressing in Europe in the 1920s-1930s to allow for longer bridge spans. Prestressing was later applied to other structures like aircraft hangars and then to flat slab construction in the 1950s. Post-tensioned flat slabs provide benefits over reinforced concrete flat slabs like reduced cracking, thinner slabs, and increased spans. The document discusses materials, design codes, comparisons to reinforced concrete, and examples of ongoing post-tensioned flat slab projects in Oman.

IRJET- CFRP Application in Retrofitting of RCC ColumnIRJET Journal
This study investigates the use of carbon fiber reinforced polymer (CFRP) sheets to strengthen reinforced concrete columns. A total of 54 columns of different shapes (circular, square, rectangular) and conditions (standard, deteriorated) are tested. The columns are loaded until failure to compare their ultimate load capacities. Standard columns achieve an average ultimate load of 15.5 tons for circular columns, 14 tons for square columns, and 13.5 tons for rectangular columns. Deteriorated columns have lower capacities of 14.33 tons, 13 tons, and 12.5 tons respectively. CFRP wrapping is then applied to standard columns to study how it increases load capacity and changes failure patterns compared to unwrapped columns.

This document provides details about innovative technologies used in the construction of special bridge structures. It summarizes the construction of a cable-stayed bridge in Bardhaman, India. Some key points:
- The bridge has a main span of 124 meters and uses precast concrete segments, steel pylons, and parallel strand cable-stay system for support.
- Advanced modeling software and wind tunnel testing were used in the design. Precast concrete slabs were used to avoid scaffolding.
- Construction involved erecting the steel pylons and deck segments, installing and stressing the 180 tons of stay cables to provide support.
- Monitoring sensors were installed to track the bridge's performance over its 100

CoVID-19 sprang up in Wuhan China in November 2019 and was declared a pandemic by the in January 2020 World Health Organization (WHO). Like the Spanish flu of 1918 that claimed millions of lives, the COVID-19 has caused the demise of thousands with China, Italy, Spain, USA and India having the highest statistics on infection and mortality rates. Regardless of existing sophisticated technologies and medical science, the spread has continued to surge high. With this COVID-19 Management System, organizations can respond virtually to the COVID-19 pandemic and protect, educate and care for citizens in the community in a quick and effective manner. This comprehensive solution not only helps in containing the virus but also proactively empowers both citizens and care providers to minimize the spread of the virus through targeted strategies and education.

• Corrosion is a dangerous and extremely costly problem and is draining the economy
silently
• Safety of infrastructures can become problematic when subjected to harsh
environmental conditions
• Steel is an old material, it’s great but often does not fit some applications!

13. Advantages of MST-BAR™ Over Steel Rebar
CONCLUSION:
MST-BAR® it is proven for its long-term saving with life of over 100 years
vs Black steel of 25 years
MST-BAR® with its proven higher performance not only will not add
additional costs to the project; it will certainly result in major savings

Tunneling (Soft eye)
Hospitals & MRI Rooms
29. Cost Study: BLACK STEEL
Chloride ions, moisture and salts will penetrate through the membrane and begin
corroding its top reinforcement
CONCLUSION: 25 years after the road construction, its asphalt surface will have
to be rehabilitated, the membrane would require replacement and the upper
reinforcement would corrode needing to be replaced. Considering the life span of
MST-BAR® at well over 100 years, the savings that it brings to any and all
construction projects is undoubtedly substantial.

30. Reducing Your Corrosion Protection by MST-BAR
When using MST-BAR the following protection can be removed by
CSA Code
Membrane
Reducing concrete cover from 70mm to 40mm
Removing C.N.I.
Reducing or Removing Asphalt completely
With Steel With MST-BAR
31. COST SAVINGS OF MST-BAR™
Transportation Costs, 4 times lower due to its 73% lighter weight
Minimum required concrete cover, 38mm for bars #2 -5 and 50mm for bars #6 -8,
(the regular steel bar concrete requires 65mm)
Increase in labor performance and less fatigue for labors during placing the bar
result in faster installation
MST-BAR® price with its proven higher performance will not add any extra cost to
the project however it will result in saving.
40-60% less expensive than stainless steel rebar while MST-BAR® has much higher
performance than the most expensive Stainless-Steel
No water proofing membrane, a unique cost-saving feature
NEVER Epoxy coat paint, re-patch the concrete or replace the rusted bars is no
longer needed
MST-BAR, does not required any maintenance
