Abstract.
The development of standardized timber bridge plans and specifications is a key element in improving design and construction practices. The bridge plans presented were developed as a cooperative effort between the USDA, Forest Service, Forest Product Laboratory (FPL), the University of Alabama, and Southern Pine Council....designing loads for AASHTO HS 20-44 and HS 25-44 vehicles, and two options for live-load deflection criteria.

Does anyone have CBIP Manual On Transmission Line Towers (Technical Report No. 9)?
Im sorry that I dont have any information about this publication except that it was published by the Central Board of Irrigation and Power (CBIP) of India. Would very much appreciate your share here.
HIGH PERFORMANCE CONCRETE STRUCTURAL DESIGNER’S GUIDE
High Performance Concrete Technology Delivery Team
Introducing . . . the Federal Highway Administration’s
HIGH PERFORMANCE CONCRETE TECHNOLOGY DELIVERY TEAM
Created to implement a mandate of the Intermodal Surface Transportation Efficiency Act of
1991 (ISTEA) legislation, the Federal Highway Administration’s (FHWA) High Performance
Concrete Technology Delivery Team (HPC TDT) motivated and helped State DOT’s to build
more economical and durable bridges using high performance concrete. The TDT, created in
1997, assisted 13 States in design and construction of HPC bridges. Hundreds of State, Federal and industry personnel were introduced to HPC technology at workshops and showcases planned by the TDT and hosted by participating DOT’s. Working with the American Association of State Highway and Transportation Officials (AASHTO) Lead States Team on HPC Implementation, the TDT influenced many additional State DOT’s to try HPC in their highway bridges.
By the time the ISTEA legislation expired, about 25 States had used HPC. Today, the TDT
continues to promote HPC and encourage states to build HPC bridges through the Innovative
Bridge Research & Construction Program (IBRCP) created under the current highway program of TEA-21. HPC is considered an innovative material and projects can be funded under the guidelines of the IBRCP.
Two primary factors led to the rejuvenation of the HPC TDT. In 1998, the FHWA created
Resource Center offices in Atlanta, Baltimore, Olympia Fields (IL), and San Francisco. These
Centers were staffed to bring training, technical expertise and technology transfer specialists
closer to state and local highway agencies. In addition, the TDT was being renewed with a
focus on field delivery of HPC technology. Accordingly, TDT members represent the FHWA
Resource Center; the Division Offices; the Agency’s Headquarters Offices of Bridge and
Pavement Technology; the Office of Infrastructure Research and Development; the Eastern
Federal Lands Highway Division; and various State DOT’s. Recognizing that earlier
technology delivery efforts were the result of key partnerships and coordination, the new TDT also includes representatives from academia and industry.

I have a problem with Maple 13. I am trying to solve a vibration problem with 40x40 and larger matrices. I am using "LinearAlgebra[Determinant]" function for creating the eigenvalues' equation. When the matrix is larger than 30x30 Maple gives an error "object too large". How can I avoid it?
