The period of vibration is a fundamental parameter in the force-based design of structures as this parameter defines the spectral acceleration and thus the base shear force to which the building should be designed. This paper takes a critical look at the way in which seismic design codes around the world have allowed the designer to estimate the period of vibration for use in both linear static...

JEL Classification J33, L85, M52. This study investigated the effects of salary structure, performance requirements, and type of business on the performance of housing agents. The participants in the study survey consisted of the employees of real estate firms in Kaohsiung, Taiwan. Restricted and unrestricted regression models were used to compare the goodness-of-fit of the regression models. A...

This paper briefly reviews the development of earthquake resistant design of buildings. The state-of-the-art of seismic design is discussed from the viewpoint of the performance criteria of buildings. These are (a) serviceability from frequent minor-intensity earthquake motions, (b) repairability from an infrequent but major-intensity earthquake motion, and (c) life safety from the maximum poss...
