NRS-22643 | Calculations Books

These are two Calculation Books detailing engineering calculations for bridge spans, impacts, stress and loadings for various parts of bridges. Also included are calculations on stress and impact loadings for locomotive rolling stock, cranes, track work etc. Custody History From 1955 until 2000 the State Rail Authority of New South Wales maintained an 'in house archives' consisting of the archival records of the Authority, its predecessor agencies and the private railway companies taken over by the government. The date ranges of the records were from 1849 until 2000. When the decision was made to close the 'State Rail Archives' the parts of the collection that were required as State archives were transferred to the State Records Authority of NSW. Those record series were incorporated into the State Records series system of archives control and were re-numbered. This series was formerly part of the State Rail Archives collection where it was identified as series R551. It may have been viewed in the State Rail Archives as series R551 and could have been previously cited as such in notes by researchers at State Rail Archives or in publications or unpublished works.

本数据集包含两部工程计算手册，详细记载了桥梁各部件的跨度、冲击效应、应力与荷载相关工程计算内容，同时涵盖铁路机车车辆、起重机、轨道工程等领域的应力及冲击荷载计算。

保管沿革
1955年至2000年，新南威尔士州铁路管理局（State Rail Authority of New South Wales）设立内部档案馆，馆藏涵盖该局、其前身机构以及政府接管的私营铁路公司的档案记录，档案时间跨度为1849年至2000年。
因决定关停“州铁路档案馆”，其中符合州级档案留存要求的馆藏被移交至新南威尔士州档案管理局（State Records Authority of NSW）。该批档案系列被纳入州档案管理体系并完成重新编号。
本数据集所属档案系列原隶属于州铁路档案馆，原编号为R551系列。其在州铁路档案馆期间或被以R551系列标识，此前州铁路档案馆的研究人员或已在相关研究笔记、出版物及未刊作品中以该编号对其进行引注。
