Abstract | Configuration, the general vertical or horizontal shape of buildings, is an important factor in earthquake performance and damage. Buildings that have simple, regular, symmetric configurations generally display the best performance in earthquake. When a ratio of the quantities such as stiffness, strength or mass between adjacent stories exceeds a minimum prescribed value, the structure is defined as being irregular. In low to moderate seismicity regions where the effects of earthquakes are normally not considered in design, we therefore can expect more percentage of irregular buildings. This research focuses on an exploration survey of typical multi-story concrete buildings in Thailand. Data collection is made by field surveys. Configuration irregularities are classified into many types (defined by UBC, 1997) and their severity will be determined. Structural indexes of some important structural components are also computed so that we will be able to see their potential failure modes. After the analysis of each individual building is completed, typical configuration irregularity patterns are identified. From the study, the main results indicate that a soft-weak story and torsional irregularity are the typical type of configuration irregularities. Shear failure has higher tendency to occur in lower zone of mid-rise and high-rise buildings column although flexural failure is always found in beam structures. Moreover, joint shear failures generally occur in all beam-column sub assemblages. |
