SOFTWARE DEVELOPMENT FOR
R/C BUILDING VULNERABILITY INDEX
AND MEMBER IMPORTANCE CALCULATION
Turkey has many active faults which have the potential to generate large
earthquakes. Recent earthquakes showed that the buildings in Turkey are not well
designed and vulnerable to earthquakes. Previous studies on the subject showed
that many structures in Turkey need to be strengthened before the next major
earthquake to minimize property loss and casualties.
A number of fast and approximate (mostly empirical) methods have been
developed in the past to process large building stock. However, there are some
important and special structures that do not fit with the general building stock and
needs special consideration (e.g., disaster management center, governmental
buildings, hospitals, tall structures, etc.). This study targets to evaluate those
important and special structures in a detailed, fast, and correct manner. The
developed software, which constitutes an important part of this study, does process
the building information several times to determine member-based importance
factors. The vulnerability index of the building will be determined using the importance of each load-carrying member and how much each member is forced
with respect to its capacity.
In order to augment user perception, a functional graphical user-interface is
designed. Software is equipped with modules that generate input files for SAP2000
analysis program, conduct dynamic and static analysis automatically, and postprocess
the generated analysis results which enable the engineer to make a
decision on the vulnerability of the structure. Program is written in C++, using
object-oriented programming technique.
The main difference between this and similar studies is the generator
program which automatically generates 3D-FE models and post-processes nonlinear
analysis results for an effective decision mechanism. In this way, more
realistic results can be obtained much faster.
As future studies, new routines are planned to be implemented to the
graphical user interface of the program which will suggest smart and engineered
retrofit/strengthening alternatives to the user.
