The Concrete Groined Arch in Filter and Covered Reservoir Construction
Thomas H. Wiggin
Appears on pages(s):
The groined arch for reservoir and filter roogs has been frequently described in good articles (as for example that by Mr. Leonard Metcalf in the Transactions of the American Society of Civil Engineers for 1900, with valuable discussions by W.B. Fuller and others), and the writer's only excuse for this paper is his participation or acquaintance with the design of a number of recent important plants in connection with which fresh consideration has been given to old problems. Incidentally some useful data, mainly drawn from other papers, but extended where convenient, are collected in the paper.
