Theatres!<br />

Yes sir, Mr. Theatre Owner! Giv,e FREE<br />

HAWAIIAN VANDA ORCHIDS and your midweek<br />

returns will look like your weekend returns<br />

. . . and we've got letters to prove it! Here's<br />

just one example from a theatre owner in Colorado<br />

— ". . . the two evenings I gave orchids<br />

away were outstanding attendance nights for midweek,<br />

and after paying for them, I had a nice<br />

profit above the cost of feature, advertising, etc.<br />

. . . anv theatre that hasn't had an Orchid Night<br />

is missing a chance to do extra business, and gain<br />

some wonderful good will." So try this testedand-proven-successful<br />

method of promoting your<br />

mid-week theatre attendance!<br />

cost, but that it will be attractive and retain<br />

its beauty for many years to come.<br />

However, when the total amount of steel<br />

permissible for building construction is<br />

severely curtailed, even the smaller amount<br />

used in conventional reinforced concrete<br />

many at times be excessive. The problem<br />

then becomes one of reducing the amount<br />

of reinforcement needed without materially<br />

reducing the strength or increasing<br />

costs.<br />

'NEW TYPE 0? ROOF CONSTRUCTION<br />

The two portions of a theatre which require<br />

the greatest amount of steel reinforcement<br />

per square foot of area are<br />

usually the roof (and its supporting beams,<br />

if any) and the balcony. The balcony of<br />

a theatre can be eliminated if necessary:<br />

but unless the theatre is a drive-in, the<br />

roof definitely cannot. It presents a problem<br />

in how to save steel without violating<br />

building codes or fire regulations.<br />

One practical solution which found its<br />

first great use in this country during the<br />

last emergency is thin-shell roof construction.<br />

Strong and eminently practical for<br />

spanning large interior areas, reinforced<br />

concrete thin-shell roofs are usually less<br />

than 31/2 inches in average thickness and<br />

require a minimum of reinforcing steel.<br />

For theatres, where a large unobstructed<br />

ground floor area is almost a must and<br />

firesafety is a vital requirement, thin-shell<br />

roofs are literally a "tailor-made" answer.<br />

PRINCIPLE IS EASILY DEMONSTRATED<br />

Without wandering too far into engineering<br />

mysteries, the steel-saving principle of<br />

strength in a thin-shell roof can be easily<br />

and interestingly demonstrated. Tear a<br />

sheet from a small memo pad or select a<br />

playing card from a deck. Now hold the<br />

sheet or card in a flat position by slight<br />

clamping pressure along one of its short<br />

edges, and place a coin on its surface. It<br />

will collapse beneath the weight. But if<br />

the same card or piece of paper is curved<br />

upwards into an arch and held in this<br />

curve by pressure of the fingers, it will<br />

support the coin and perhaps additional<br />

ones as well. The thickness of the card or<br />

paper has not been increased, nor has it<br />

been reinforced by other materials. Its<br />

shape and the method in which it is supported<br />

have been changed, and these make<br />

the difference in its load-carrying capacity.<br />

When the card or paper is held flat, the<br />

weight of the coin is resisted by bending<br />

forces only. When arched, the weight is<br />

resisted by thrusts acting downward over<br />

the curve formed by the shell and outward<br />

against the fingers supporting and maintaining<br />

the curve. The load stresses are<br />

distributed.<br />

The principle of strength of a domeshaped,<br />

thin-shell roof is illustrated by a<br />

table tennis ball, a remarkably tough and<br />

strong object for its thinness and weight.<br />

Half of a table tennis ball supported I'<br />

tween two books wiU carry weights ma<br />

times those it would be capable of suppoiing<br />

if flattened and placed over the saiarea.<br />

The reason is its curved, thrc<br />

dimensional shape. Every portion of ,<br />

dome where a load may be placed is elas t<br />

cally supported by the portions surround!<br />

it, and these surrounding portions provi<br />

forces to resist the load.<br />

Just what does all this mean to a pre<br />

pective theatre owner? As pointed out b<br />

This photograph shows the concrete masonry ce<br />

struction of the Bexley Theatre, shown also<br />

page 35, before the application of light-color<br />

stucco. Use of exposed concrete masonry is<br />

method of conserving critical materials.<br />

fore, a theatre roof must usually span lar<br />

interior spaces unsupported by colum:<br />

which block visibility. A flat roof like tl<br />

sheet of paper, card, or flattened tab<br />

tennis ball, is not capable of supporting<br />

heavy load over large interior areas witl<br />

out beam support and or a substanti<br />

amount of reinforcement. But when archi<br />

or built in dome shape, a concrete roof<br />

remarkable thinness . . . much thinn<br />

than is normally possible in a flat ro<br />

. . . can safely span long distances wii<br />

a relatively small amount of reinforC'<br />

ment.<br />

Naturally the smaller the amount •' |<br />

reinforcement needed, the less steel coi '<br />

sumed.<br />

Prior to World War II, thin-shell roc'<br />

had been in use for some years in Euro] ;<br />

and South America, and a few had bee'<br />

;<br />

constructed in this country. But it was ni<br />

until World War II<br />

that this type of cor<br />

struction found any appreciable measure i<br />

use in North America. Its popularity hi<br />

grown for gymnasiums, auditoriums, ai:<br />

craft hangars, and other buildings when<br />

a large clear ground floor area is neede If<br />

Its use for theatres should be stimulate I<br />

by current steel restrictions, and its popi<br />

larity should increase even more rapid<br />

as more architects become familiar wit<br />

its<br />

potentialities.<br />

PRESTRESSED CONCRETE<br />

Another steel-saving method of reii<br />

forced concrete construction, and one i<br />

the most talked about developments in ei<br />

gineering circles today, is prestressed cor<br />
