Penang Bridge Stay ReplacementPresenter: Chris Hendy, Head of Bridge Design and Technology
Tuesday, October 19, 11:00 a.m. - 11:30 a.m.
Atkins
Penang, Malaysia
A structural assessment of the 225-meter cable-stayed Penang Bridge in Malaysia detected a bar break on one cable, leading to the replacement of 117 cables that were vulnerable to similar breaks. Atkins used RM Bridge to carry out the global analysis of the structure, taking into account the staged construction and effects of creep and shrinkage. Second order analysis, including the effects of cracking, determined impacts on slender tower elements. |

High-Point Rendel
Chittagong, Bangladesh
The Third Karnaphuli Bridge spanning the Karnaphuli River in Bangladesh is a significant new landmark in the port city of Chittagong. Designed to withstand earthquakes, the 950-meter crossing consists of three 200-meter extra-dosed main river spans, two 115-meter side spans, and a 120-meter approach viaduct with 20-meter spans. The design-build contract stipulated that the main bridge structure have the extra-dosed, concrete cable-supported deck - a state-of-the-art building technique pioneered in South East Asia and Japan. |

T.Y. Lin International
San Diego, California, United States
The Harbor Drive Pedestrian Bridge in California will realize the 100-year vision to link the historic Balboa Park with the scenic San Diego Bay. The bridge will provide a safe pedestrian crossing over Harbor Drive and existing train and trolley tracks. T.Y. Lin International (TYLI) designed the $24 million bridge to be one of the longest self-anchored suspension bridges for pedestrians in the United States. |
