Ian Firth: Bridges should be beautiful
Ian Firth: Neden köprülerin çok güzel olması gerek
Ian Firth designs bridges all around the world; some are very long and cross over wide rivers or sea channels, and some are really short and in the middle of towns and cities, but "all of them are unique and special in their own way." Full bio

what it would be like not to have any?
a civilization without bridges
bir toplum düşünmek çok zor
of human society,
across a river or an obstacle.
güvenli geçişten çok daha öteler.
living in poor, rural communities
kırsal kesimlerde yaşayan
and I take for granted:
access to markets ...
like Bridges to Prosperity
harika organizasyonlar
this is in Rwanda.
burası Rwanda.
immediately around the bridge,
yakınında olanlara değil,
for an awfully long time.
uzun zamandır hayatımızda varlar.
because it's a very durable material.
çünkü çok dayanıklı bir materyal.
the development of technology
with the materials
materyalleri kullanarak
is a wonderful example --
suaşıtı.
built using massive stones put together,
oluşturulmuş harika bir teknoloji,
birleşme yerlerinde harç yok.
these suspension bridges,
to build these bridges.
örülmesi sağlanmış.
they rebuild this every year?
yeniden inşa ediyorlar.
is not a durable material.
since Inca times.
beri hiç değişmemiş.
symbols of their location.
elbette çok aşinayız.
and Sydney are well familiar.
with the name of the place,
that in the war in 1993
until the bridge was reconstructed.
halk neredeyse kimliğini kaybetmiş.
features in our landscape --
devasa önem taşıyorlar.
sometimes there's small ones --
bazen küçük ayrıntılar da var
to make our bridges beautiful.
yükümlü olduğumuza inanıyorum.
in the South of France.
büyüleyici Millau Viaduct.
and British architect Lord Foster
ve İngiliz mimar Lord Foster
ortaya çıkarmak için
synergy of architecture and engineering.
in the mountains in Switzerland --
tarafından yapılan Salginatobel Köprüsü...
and rather delicate bridge
Tintagel Kalesi için yaptığı
and beautiful designs
in three convenient categories,
of the structural system
as their principal support.
değerlendirilebilir.
is the way a beam will behave --
kirişlerin akıbetini belirler.
way of operating for an arch.
sıkıştırma ilk başlıca faaliyettir.
you need to go lightweight,
ihtiyacımız olan hafiflik,
for variety is enormous.
for innovation and ingenuity
bir yenilik ve maharete,
around these types.
geliştirme yetisine sahip.
happens relatively slowly in my world,
nispeten yavaş gelişiyor,
that happen in mobile phone technology
teknolojilerle kıyaslandığında.
technologies and so on.
istenmiyor gibi görünüyor.
can be summarized in one word:
bir kelimeyle açıklayabiliriz:
risk idaresi yapar.
that loads will be excessive on one side
veya diğer kısmın güçsüz olacağı
too low on the other side.
are full of uncertainty usually,
for safety between the two, of course.
olduğundan emin olmamız gerekiyor.
and get their sums right
ve doğru çıkarım yapmak zorunda,
when things like this happen.
çok fazla endişe veriyor.
for these tragedies,
happens quite slowly.
on their projects, obviously.
bunun olmasını istemez.
if I wasn't wanting to innovate,
iyi bir mühendis olamam
of knowledge and strength
penceresinden bakmamız lazım.
since the beginning of time --
bundan ders çıkardı,
this film before --
Tacoma Narrows Bridge collapse
as "Galloping Gertie"
for quite a long time,
böyle iki yana sallanıyordu,
called Leon Moisseiff,
tarafından tasarlanmıştı,
just that little bit too far
suspension bridge development
asma köprü gelişimini
about doing another suspension bridge.
bir asma köprü yapmayı düşünmedi.
to what had happened.
güvenlik için tepki veriyordu.
gerçekten yapıldığında
a technological step change.
streamlined cross section
very torsionally stiff --
yani bükülmeye dayanıklı,
at Tacoma would not happen here.
bu örnekte asla olmaz.
important for long spans,
hafiflik gerçekten önemli
to want us to build longer spans.
inşa etmemizi istiyor.
which is a bit longer,
bir tanesi üzerinde çalışıyoruz
the Messina Bridge in Italy,
Köprüsü'nü tasarladık.
with construction one day,
to Messina in a moment.
which uses that tension principle
uzun kirişli köprülerden diğer bir tür
a whole load of these right now.
in Vladivostok, Russia --
Vladivostok kentindeki Russky Köprüsü.
about long-span and lightweight.
konusuna geri dönelim.
as an example.
the capacity of the main cables --
kapasitesini temsil ediyor -
of that capacity
is there to support:
steel wire available to us,
çelik kabloyu kullansak
around about five or six kilometers
beş ve altı km arasında
carbon fiber in those cables,
karbon fiber kullanırsak
necessarily the way to go everywhere.
her yere gitmek için şart değil.
of other challenges associated with them,
beraberinde getiriyorlar,
veya akarsudan geçmek için
a wide estuary or a sea crossing.
were somewhere like Gibraltar,
Gibraltar gibi bir yerdeyse
multiple superlong spans
inşa etmemiz gerekir,
something spectacular, wouldn't it?
that one finished in my lifetime,
böyle bir köprü göremeyeceğim,
for some of you guys.
beklemeye değer bir şey olacak.
which I think is really exciting.
bir şeyi paylaşmak istiyorum.
across very deep water in Norway,
çok kirişli bir asma köprü
are prohibitively expensive.
aşırı derecede pahalı demek.
multispan suspension bridge.
but nothing like this.
ama hiçbiri böyle değildi.
and held down --
against those buoyancy forces,
have to be tied together,
bağlı olması gerekiyor,
would just wobble around
about the places around the world
to the possibility of a bridge
olabileceğıne ihtimal vermiyordu,
by the Norwegian Roads Administration,
tarafından yapılıyor
enable development --
gelişim konusunda,
like Rudy Ricciotti here,
birinin ellerindeyken
performance fiber-reinforced concrete.
fiber güçlendirilmiş beton diyoruz.
and it's really durable,
sculptural quality.
elde ediyorsunuz.
sönük olduğunu da kim söyledi?
of other new technologies and things
and AI and all of that,
which I alluded to earlier on.
bir şeye dikkatinizi çekmek istiyorum.
they need to be elegant;
gerektiğine içten inanıyorum;
bir zaman için tasarlanıyor.
for an awfully long time.
whether it overran a few months.
birkaç ay uzadığını hatırlamayacak.
does exactly the opposite.
tamamen tersini yapar.
mediocre, ugly environments --
çevreler inşa edersek -
numb to that stuff --
duyarsızlaştığımız kanısındayım -
a large-scale vandalism,
through a design competition.
to those people who procure our bridges
ve diğer yapılarımızı tedarik eden
which is often the key.
is one way to get good design,
sadece bir yol,
of procurement going on
against good design.
a bit slowly sometimes in my world.
biraz yavaş işliyor.
about what we can do with it.
konusunda heyecanlıyım.
hayat kurtarmak için,
of long-span technology
sınırları uzatmak için
elegant and beautiful stuff

Why you should listen
As Ian Firth writes: "I have been fortunate enough to work on some of the world's most amazing bridges, and I lead fantastic teams of engineers involved in the design, construction and management of bridges all over the world. Since 1990, when I became a Partner in Flint & Neill, the UK engineering consultants who I joined as a young graduate in 1979, I have helped to grow the firm into one of the world's leading bridge design consultancies. Flint & Neill joined the Danish COWI Group in 2008 and rebranded as COWI (UK) in January 2017.
"I love the fact that my work has included some of the very biggest bridges as well as some much smaller and more intimate ones. The big ones include the huge 3.3 km-long single-span suspension bridge over the Messina Strait in Italy and the 1 km span Stonecutters Bridge in Hong Kong. The smaller ones include Copenhagen's new Inner Harbour Bridge, the Third Way Bridge in Taunton and the Swansea Sail Bridge in Wales. In fact, one of my favorites is the smallest: the little Bridge of Aspiration in London's Covent Garden, which is only 9 meters long! Working alongside bridge architects, I always try to weave elegance and beauty into my designs alongside the essential safety, economy and other factors, so that my bridges are popular as well as efficient and durable. Altogether, I reckon I have designed well over 100 bridges, but sadly not all of them have been built!"
