Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

F-i Appendix F Concept 2 Large-Scale Laboratory Bridge Instrumentation Designation, Nominal, and Measured Locations

F-1 F.1 Concept 2 Laboratory Specimen Instrumentation Designation The instrumentation for the concept 2 laboratory specimen was labeled as described in this section. An example designation is given in Figure F.1. 1. The first character indicated the type of gage. • C = VW concrete embedment gage • T = Strand resistive gage • M = Polyester Mold concrete resistive gage • P = Polyester Wire surface resistive gage • S = VW spot-weldable gage • V = 120Ω waterproof resistive gage • W = 350Ω waterproof resistive gage 2. The second character indicated the span number. There was only one span in this bridge, however this digit was maintained to facilitate comparison with the instrumentation in the Concept 1 bridge. This value was 1 for every instrument in the Concept 2 bridge. 3. The third character indicated the precast section within the span in which the gage was located. • N = North precast section • S = South precast section • J = Joint There was a hyphen after the third character. 4. The fourth character indicated the position of the gage along the precast section. • 1.0 = East end of span • 1.5 = 1/8th point of the span • 2.0 = 1/4 point of the span • 2.5 = 3/8th point of the span • 3.0 = 1/2 point, or mid-span • 3.5 = 5/8th point of the span • 4.0 = 3/4 point of the span • 4.5 = 7/8th point of the span • 5.0 = West end of the span There was a hyphen separating the fourth and fifth characters

F-2 5. The fifth character indicated where the gage was located in the depth of the cross section. Numerical values representing the depth start at the bottom of the section and increase towards the top of the section. a.) For longitudinal instrumentation: i. 0.5 = Gage was located on the bottom face of the precast unit ii. 1.0 = Gage was located on the bottom prestressing strand iii. 2.0 = Gage was located above the precast flange iv. 2.5 = Gage was located below the precast web v. 3.0 = Gage was located above the precast web vi. 3.5 = Gage was located near the top surface of the member b.) For transverse instrumentation: i. 1.0 = Gage was located above precast flange at same depth as transverse hooked reinforcement ii. 1.5 = Gage was located at mid-height of cage stirrup iii. 2.0 = Gage was located above precast web 6. The sixth character indicated the orientation of the gage. • L = Longitudinal • T = Transverse There was a hyphen after the sixth character. 7. The seventh character indicated the number of the gage at that position. a.) For longitudinal instrumentation i. 1 = For gages located closest to the outside flange (farthest away from the interior precast joint) iii. n = For gages located nearest to the inside joint b.) For transverse instrumentation i. 1 = For gage located farthest south in gage group iii. n = For gage located farthest north in gage group

F-3 Figure F.1: Concept 2 Laboratory specimen strain gage designation example F.2 Measured Locations of Concept 2 Laboratory Specimen Instrumentation All of the instrumentation in the laboratory specimen was measured to the nearest ¼ in. The sign convention of the gage ordinates is shown in Figure F.2. The X axis was measured in the E-W direction from the centerline of the pier (E positive), which was located 2 in. from the end face of the precast unit and corresponded to the center of the concrete pier. The instrumentation in the Concept 2 bridge was designed to correspond with the naming convention utilized in the Concept 1 bridge, where there was a 4 in. gap between the two spans at the concrete pier. The Y ordinate was measured in the N-S direction from the joint (N positive); the Z axis was measured in the vertical direction from the bottom of the precast sections (upward positive). The measurements are given in Table F.1. M1J-3.0-1.0T-1 Location Along the Span: Midspan Location within the Depth: Gage above precast flange Orientation of Gage: Longitudinal Type of Gage: 350 ? Waterproof Gage Span Location: West Span North/South Location: North Precast Section -span Transverse 12 Ω conc ete gage Span 1 L cated ne r Join Gage Number: Southernmost gage in gage group
