Steel or concrete
In developing a structure of each owner, architect, engineer and entrepreneur, the question should be: if there must be concrete or steel? ... With the steel in seismic areas, it is customary to have large beams and columns for the building to support the movement or arising needs of the earthquake. Often these requirements are in areas demanding than the requirements for seismic resistance of buildings.
As the promotion ofSystem of reinforced concrete has progressed in recent decades, one can say that now, in steel and concrete can be used for structures in seismic areas, such as steel and concrete have problems with quality control, concrete or steel is really the same thing ?
Better Concrete
In Los Angeles, CA bar, a tower of 23 floors with a small block of visible support and has been developed. The seismic capacity is 33% stronger than any other buildingaround him. The explanation of this model was psi through engineering research and high reactivity metakaolin admixture to improve the strength of concrete, 12,000. Therefore, the materials to be neglected in building the structure has not, in deciding on concrete or steel.
"When it comes to reducing the size of the square columns, billable square meters," said Edward Kirk, pre-edited directory of the construction project of San Mateo-based general contractor WebcorBuilders, in other words, concrete or steel requires the efficient use of intelligent materials constructed in seismic zones. It 'better to invest a little' more in research and technology to achieve greater profits and better facilities in seismic zones of high, if you choose concrete or steel structures.
Brick in seismic zones
Many may say that is not in the bricks of the type of material you want to use for the building in high seismic zones would be, but some owners haveAround it. Despite the difficulties resolved, Swiss architect, was appointed by Mario Botta, is in stone the San Francisco Museum of Modern Art Block To resolve this problem, it is fragile and unstable brick, brick-faced precast panels are secured by a resistance built the second frame. This method allows the inclusion of the brick building with complex geometric patterns of bricks, shapes, sizes, and everyone in the assembly over. After the production of such panels "seismic, push-pullThe links are used to connect the panels to the frame of the building in relation to ...
