The impossibility of drawing up fixed rules for reinforced concrete construc- 
tions generally by corporations and municipalities was referred to, The chief safe- 
guard to be employed is that of stringent tests after the construction is finished. 
In cases where much vibration is feared, from running machinery or other causes, 
ferro-concrete is admirably adapted to minimise the trouble. 
2. Some new Uses for Reinforced Concrete! 
By W. Noste Twetvetrees, M.J.Mech.#., Assoc. M.L.E.E. 
So many papers have been read of late discussing the general principles 
governing the design of reinforced concrete structures and describing works of 
familiar character in which reinforced concrete has been adopted as the material 
of construction, that the author thought it well to follow a less frequented path. 
Under the heading of ‘New Uses for Reinforced Concrete’ he considered 
some types of construction that have not yet been applied in this country, others 
that have been adopted only recently, and others again that are not new in them- 
selves, but are very suitable for employment in novel directions. 
In the first category may be placed such constructions as railway sleepers, 
standards for overhead electric cables in power transmission and electricity distri- 
bution systems, and poles for telegraph and telephone wires. The paper contained 
particulars relative to the design, construction, and application of such accessories 
as these, which are now coming into general use on the Continent and in America. 
In the second category was considered the employment of reinforced concrete 
to dock engineering, as illustrated by the Scotstoun Dock on the Clyde—the first 
example of its kind in Great Britain ; of coast defence and harbour works, as illus- 
trated by the sea wall and protective slopes at West Hartlepool, groynes near 
Brighton, and a breakwater near Waterford ; and of long-span bridges for main- 
line railway traffic and for crossing important rivers, as exemplified by typical 
structures in this and other countries. 
In the third category the author indicated the special advantages to be 
obtained by the adoption of reinforced concrete as a material for the construction 
of railway-station roofs, locomotive depéts, and bridges over railway lines. In 
all such structures steelwork is particularly liable to corrosion by reason of its 
exposure to steam and destructive gases from locomotive engines and boilers. 
To illustrate the adaptability of reinforced concrete to these new uses, the author 
gave brief particulars of roofs that are akin to those generally built in steel for 
covering railway stations, of a locomotive depot erected on the Jura-Simplon line, 
and of highway and foot bridges over railway lines. 
Finally he alluded to the method successfully adopted on the Continent for 
preserving steel bridges by encasing them in concrete, a course that is commended 
to the attention of railway companies and highway authorities in places where the 
corrosive effect of locomotive fumes is a constant source of trouble and expense.
