CHAPTER 4 SUPERSTRUCTURES

The 30 Superstructure plans show beam sizes, beam layout, and superstructure concrete limits It is important to not begin detailing reinforcing steel until the 30 superstructure plans have been checked by the designer/checker To draw the superstructure up to this level of completion, the detailer requires the following information:

SUPER STRUCTURE & SUB STRUCTURE

superstructure is an upward extension of an existing structure above a baseline This term is applied to various kinds of physical structures such as buildings, bridges, or ships The word "superstructure" is a combination of the latin prefix, super, (meaning above, in addition) with the Latinstem word, structure, (meaning to build or to

ADVANCED-ABSORBER MICROBOLOMETER SUPERSTRUCTURE LEONARDO DRS

Superstructure offers lower resistance to room temperature variances Decreasing resistance leads to lower power requirements Devices with higher resistance also adversely output greater noise levels The Advanced-Absorber Superstructure is optimized with lower resistance to help mitigate noise and decrease power input
