This document provides a summary of the design of a proposed 37m single span bridge with precast concrete T-roff girders. Section 2 describes the bridge design, including using LUSAS MODELLER software to model preliminary box girder sections and layout.

PSC Super T-Girders are currently the most prevalent girder type for spans in the order of 25 – 36 m. Alternative ‘Wide Flange I-Girders’ now have type approval for designs where spans may be up to 46 m. Wider flanges for this girder type may also be used (shorter spans) to reduce the required number of girders.

这个版本被叫做troff，因为它是排字机（typesetter）的roff。 为此，troff的发音应该是t-roff而不是trough。 随troff而来的有nroff，它是为针式打印机和字符终端设备产生输出的。

The Teeroff beam is a progression of the Super T beam developed by VicRoads' staff in the early 1990s. The Super T beam was developed in close cooperation with industry and contains many desirable features which the construction industry has endorsed by the extensive use of Super T beams on short to medium span bridges.

troff格式化打印机和字符终端的文本，是 Unix 历史上最重要的软件之一。像 roff，nroff 和 groff 一样，troff 是由 Jerome Saltzer 在 20 世纪 60 年代中期为麻省理工学院的 CTSS 操作系统编写的名为 RUNOFF 的文本

2014年5月4日 · “所见即所得（WYSIWYG，What you see is what you get）”编辑器可以使简单的工作更简单，却无法完成某些复杂的工作。nroff/troff是UNIX下经典的typesetting工具，groff是GNU的*roff实现，并对troff的功能进行了增强。与LaTeX相比，体积较小，且大多为*nix自带，使用 …

Westkon has developed superior manufacturing capabilities to produce precast concrete elements of large dimensions. We are capable of delivering an extensive product range for specialised span and loading capacities that are suitable for large scale infrastructure projects.

tensioned tee-roff beams with a cast insitu reinforced concrete deck composite with the tee-roff beams. The beams are simply supported spanning between pier lines. Pier lines consist of reinforced concrete pier beams on reinforced concrete columns and piles. There are expansion joints at all abutments and at 3 locations along the

Delta has been manufacturing and supplying precast prestressed concrete TeeRoff Beams to numerous Main Roads projects throughout Western Australia since 2002. Projects supplied are located as far north as Kununurra down to Esperance in the far south.
