لماذا المهندسون لايصممون البناء ليقاوم الزلازل- - What is the meaning buildings are designed to crack or collapse in earthquakes with a view to saving the economy
Engineers have a responsibility to discuss earthquake risk with clients to better inform them. While building codes aim to protect life safety, they allow significant damage that leaves communities unprepared. Engineers should do more to explain risks like larger-than-code earthquakes and promote resilience. Discussing risk with clients, schools, and colleagues can help create a safer world by raising awareness of natural hazards and how to mitigate risks.

Engineers must take time to discuss earthquake risk and other natural
so clients are better informed and the world a safer–ds with clientshazar
place.
As engineers we have a responsibility to use our knowledge to help reduce
earthquake risk, both human and economic. But do we do enough?
Sure, we do to some extent. As part of the Aceh post-tsunami reconstruction one of
the critical issues was explaining to the NGOs and local population what the risk
was and how this could be avoided in the future. And the REDi Rating System gives
owners, architects and engineers a framework for earthquake resilience.
Yet I think we simply don’t talk enough about risk.
How many engineers tell their clients that a code-based design could leave their
investment damaged beyond repair? Current building codes do not focus
onearthquake resilience – the ability of an organization or community to
quickly recover after a future large earthquake. The code’s objective is only to
protect the lives of building occupants.
This means significant damage to the building structure, architectural components,
facades and other elements is allowed as long as the code objective is met. It is
therefore not surprising that when a major earthquake strikes an urban region the
losses are large and the general public is left to wonder why. The Christchurch
earthquake in February 2011 is a prime example of this.
How many of us point out that there is a chance that the earthquake ground motion
could be much bigger than prescribed in the code? The code ground motion is
5. 5
based on a chance of occurring, such as say getting four numbers in the Lottery.
However, there is always the chance you may get five or, if you are very lucky, six
numbers. There is also a degree of uncertainty in what is still a very young and
developing science.
These are difficult conversations to have, but they’re essential if we are to open
people's eyes to the risk.
Why don’t we all ask to talk to our children's schools to explain what they can
do to mitigate earthquake risk? By doing this people will become more aware
of the natural environment and how they can protect themselves. For example
it is statistically safer to stay in a building and cover yourself rather than
running out and being hit by flying masonry.
And how many engineers have attended conferences, such as the
recent 2ECEES in Istanbul and learnt new things but then not communicated
these to their colleagues back home?
I spoke at 2ECEES and also learnt new things, such as the extensive
experimental testing work carried out under the SERIES project and will try
my best to help disseminate this knowledge.
If I had one piece of advice for my fellow engineers it would be this: Please
consider these questions and take some time to discuss earthquake risk and
other natural hazards, so your clients are better informed. Hopefully, it’ll make
our world a safer place.

Report?
To who should speak first About
?the risks of earthquakes
- All engineering codes and responsible parties about the construction of
buildings and acclaim Require that construction be robust and resistant to
earthquakes and natural disasters.
In addition to the engineer and the designer and government agencies
Responsible for achieving security and public safety of the citizens as well
To achieve economic factor but not at the expense of the lives of citizens
- To design buildings to withstand earthquakes and natural disasters
Determined by engineering codes and regulations urban and not the
customer or the owner The building, which does not care, but profiteering
and fast if it returned to him dollars and the possibility of not design for
earthquake resistance
- Structural engineer designer does not discuss the seismic risk with the
customer never It is designed in accordance with the applicable code
engineering and system engineering profession In the country where
construction is hailed.
- Discussion of the dangers of earthquakes in schools and forums will not
delay or offers something Reduce the size of the disaster
- Not fear but the fear of the earthquake and post-earthquake tragedy
Hunker down under the table or the bed or in the closet, is not the answer
Could collapse ceilings and columns, and the situation is worse
7. 7
- As well stay at home and do not leave may be the most dangerous of
Departure May fall interior walls and partitions blocks above the heads of
occupants.
- And the most dangerous of all seismic repercussions may follow another
streak Much larger than the first tremor lead to the collapse of the building
above the occupants
- And this is illogical and untrue to ask citizens
How to behave during disasters and earthquakes are not sure and confident
What is the best and most appropriate to stay at home or to escape to the
street during the earthquake But this does not prevent the awareness of
citizens and a statement that both roads and risksAnd return him to take
the appropriate decision.
- But the important thing is to control the state and the government to work
on the engineering and design of earthquakes and the health of the study
and implementation Civil Defense is the first and last official
About the lives of the citizens and help them during disasters Computer
Hotline Yes, we should first discuss the seriousness of the disaster from
earthquakes and other With officials from the government and to be fully
prepared and equipment
And provide help and shelters for those affected by the disaster.
- For what came in the codes and references of engineering studies and
programs Buildings resistant to earthquakes are correct and economic way
Will not go into now explained
- But humane and economical at the same time because they are interested
in human life first And the citizen can restoration and construction of new
construction, but can not be compensated
The lives of the citizens of New
- Design ordinance says we design the building almost half the magnitude
of the quake On the basis of the joints should form sulfides in sentence
construction seismic We must crack construction remains steadfast, and
the possibility of exit dwell And restoration can be built and returned to
service
- In this way we maintain the public safety of the citizens
At the same time we have provided millions of dollars on economic owner
and State If the earthquake happened can renovate that building millions If
the earthquake did not happen and has provided millions of home
8. 8
can finally say:
- Engineering and construction is in first-class safety and keeping the
public safety of the citizens- not economy and provide millions
- But we support the opinion of the writer must build a solid and be
steadfast before the occurrence of earthquakes We must reconsider the
ordinance economic design and form plastic joints
- Because no design engineer nor humanly not legally accept the design
house building handicapped irresistible earthquakes
Fully and is subject to cracking and cracking and displacement dwelling
under the pretext of saving the economy
- So it does nothing to prevent reconsider these assumptions form the
joints and other sulfides Even though the design has been forced to double
the expected magnitude of the quake and add some shear walls
Or decrease the number of floors or the value of the purchase of housing in
exchange for preserving the safety of citizens and the safety of their homes
Can not accept, apartment or condo building in advance know that it will
collapse or crack Upon the occurrence of the earthquake and its owners
become homeless.

Upon the occurrence of thecrack or fall apart over the heads of residents
Under theearthquake and occupants become homeless or displaced
pretext of saving and the economy
-Why do not designed to build on the full force of the earthquake and more
so as not to crack and fall apart and re-restored and strengthened again
Why rely on things fake unreliable form of arthritis sulfides in the resistance
elements of the earthquake And the arrival of its resistance to the Teflon
region and distracting power of the earthquake
and that's for sure not going to happen for the presence of a single cause
Poor implementation of the low-quality materials to the lack of experience
ness and suicideIt's a sample of mad-
