Evolution of Bridge Construction – Non-metallic Bridges
Wednesday August 1st, 2018
The “Non-Metal Bridge” that eliminates the use of steel members, such as steel reinforcements and prestressing steel, was developed and FRP rods are used as prestressing tendons to resist tensile force of concrete. Moreover, fiber concrete is selected to increase the shear capacity. The non-metallic deck slab with FRP rods as transverse tendons in the slab was conducted wheel load running tests to verify the fatigue of the structure. The Non-Metal Bridge will be constructed by a precast segmental construction method using a butterfly web structure. A half scale butterfly girder was built by using segmental method and tested to confirm the strength of the joints between segments. It was sufficiently durable. This leading-edge technology leads life of structures much longer, which concrete basically has.
Akio Kasuga, Dr. of Engineering, born in 1957, received his civil engineering degree from the Kyushu University, Japan in 1980. He has been working for Sumitomo Mitsui Construction as a bridge designer since 1980. He is a fib Presidium member and a board member of Japan Prestressed Concrete Institute

The Construction of Sheikh Jaber Al-Ahmad Al-Sabah Causeway Project (Main Link) across Kuwait Bay between Kuwait City and Subiyah area.
Thursday August 2nd, 2018
The The 36-km Sheikh Jaber Al-Ahmad Al-Sabah Causeway Project (SJSC) is one of the largest and most prestigious transport infrastructure endeavors in Kuwait and the region The main goal of this Link is to facilitate the traffic movement to Subiyah by drastically reducing the 70-minute ride on the current highways to a 20-minute ride on the Causeway. Subiyah region in the north of Kuwait where the new Madinat al-Hareer (Silk City) is planned to be constructed. The ambitious Silk City project aims to revive the ancient silk trade road. A major free trade zone will be established in Silk City, linking the Gulf to Central Asia and Europe, thus helping transform the country into a commercial and investment hub.
Al-Hassan received his civil engineering degree from the University of Colorado, Boulder, USA in 1986.. During his 31 years of professional experience, mainly with the Ministry of Public Works in Kuwait, Mr. Hassan was responsible for managing various contracts with major international consultant firms involved in infrastructure projects in Kuwait.

The Exciting Future of Precast Pre-stressed Concrete Bridges in North America
Friday August 3rd, 2018
Recent years have witnessed tremendous developments in concrete materials technology. Concrete mixtures have recently been designed using advanced theories of particle packing to create 150 MPa compressive strength. With 3,000 MPa, high aspect ratio, steel fibers, high tensile strength, ductility and toughness are created. As a result, Ultra-High Performance Concrete (UHPC) combined with innovative structural engineering can produce bridge superstructures that are half the weight of conventional systems and many times stronger and more durable. This presentation will illustrate potential applications for short and medium span bridges using conventional as well as Accelerated Bridge Construction (ABC) techniques of curved post-tension and precast concrete.
