Determination of basic form and the first oscillation period for buildings using approximate methods
This paper discusses the application of approximate methods for determination of the first oscillation period for cantilever and frame structures, frequently used in civil engineering construction works. Based on oscillation analysis of different cantilever and frame structure examples, the paper suggests oscillation forms that can be used for approximate determination of the first oscillation period. The significance of the determination of the basic form and the first oscillation period using approximate methods is in the possibility of estimation of horizontal dynamic loads in preliminary structure system analysis. Computerized processing of dynamic characteristics of complex structural systems requires a number of data registrated, therefore occurrence of errors is highly possible during such a registration. In addition, approximate methods can also be founded useful in confirmation of the first oscillation period calculation results for civil engineering structures.
