7 Project Location EDMONTON ANCOUVER CALGARY REGINA WINNIPEG MADISON TORONTO BLOOMFIELD ALBANY KLAND SACRAMENTO DENVER CHICAGO ALEXANDRIA SAN DIEGO PHOENIX AUSTIN LAFAYETTE Louisiana Department of Transportation and Development (LaDOTD) Page 7
8 Project Summary Future 5.5 mile segment of limited access highway that will extend I-49 through I-10 to the Lafayette Regional Airport Features 2.75 miles of elevated freeway Page 8
9 Project Goals Determine the best-value bridge and structure alternatives U-Girder design is part of a larger Bridge Development Report that also studied steel girders and concrete segmental Work within the confines of a Context Sensitive Solutions (CSS) design that is intended to obtain input from all stakeholders Utilize a closed, trapezoidal shaped structure for the mainline structures Maintain a minimum span length of 150-feet Page 9
10 Project Summary Criteria Girder Section Midas Modeling
11 Criteria Prepared by AECOM with input and acceptance by LADOTD LA Spec LADOTD Standard Specifications for Roads and Bridges (2006) BDEM LADOTD Bridge and Evaluation Manual (2015) AASHTO AASHTO LRFD Bridge Specifications, 7 th Edition (2015) Static Loads Post-Tensioned Concrete γ = 155pcf Future Wearing Surface σ = 25psf 42 F-Shape barrier w = 521plf Pre and Post-Tensioned Concrete U-Girder Page 11
12 Criteria Live Loads Louisiana Vehicle Live Load 2011 (LADV-11) o Product of the force effects produced by AASHTO HL-93 and a BDEM magnification factor o LADV-11 is a multiplier on the load magnitudes AASHTO Lane definition and multiple presence factors Live load deflection limited to L/800 using either Truck alone or 25% Truck with Lane Pre and Post-Tensioned Concrete U-Girder Page 12
13 Criteria Temperature Loads Uniform Temperature by AASHTO Procedure A, base temperature of 68 Neglect Temperature Gradient Creep and Shrinkage Loads Relative Humidity 75% Wind Loads Per AASHTO Section 3.8 Centrifugal Force Per AASHTO Section 3.6.3, design speed of 60mph (Urban Freeway) Braking Force Per AASHTO Section Dynamic Live Load Allowance Per AASHTO Section Pre and Post-Tensioned Concrete U-Girder Page 13
14 Criteria Load Factors BDEM has a load factor table that supersedes AASHTO Tbl o Service III LL factor 1.00, increased from AASHTO 0.80 o Extreme Event I factor 0.25, decreased from AASHTO 0.50 o Redundancy Load Factor 1.10 for girder spacing greater than 12-ft Materials Post-Tensioned concrete f c = 6ksi (LADOTD Class P) Precast-Prestressed concrete girders f c = 8.5ksi (LADOTD Class P) Elected to use f c = 10ksi (LADOTD Class P) o Release strength of f c = 7.5ksi Pre and Post-Tensioned Concrete U-Girder Page 14
15 Criteria Assume shoring towers at every splice for support until girders are made continuous by post-tensioning Neglect curvature of superstructure in the Midas models Girders will be chorded along the unit with kinks at the splice locations The curvature is large enough that centrifugal forces are minimal Post processing of Midas results Allowable stresses were calculated based on AASHTO and BDEM Load calculations prepared in advance of model building Pre and Post-Tensioned Concrete U-Girder Page 15
