Abstract: Castellated and Cellular beams are an alternative solution to improve strength and reduce deformation of the members which results in better performance of the overall structures. However, for other cellular members than the beam, for instances, column, connection part and frame, only small amount of researches can be found. Yet, in construction, it is practically designed without sufficient data and verity. Hence, in this thesis, the application of Cellular beam, Cellular column, rigid connection with Cellular beam-to-column and web-tapered Cellular gable frame are studied thoroughly to get insight into the various key behavior and be a guideline for utilizing such members effectively. In the study, the equation is proposed for evaluating the lateral torsional buckling moment of Cellular beam. The equation for evaluating the web-post buckling of Castellated and Cellular beams is also proposed. It is also found that the efficiency of Castellated and Cellular beams is dominant for the beam with the length of at least 30Rx. The application of Cellular beam and column can increase strength and improve energy dissipation of rigid connection under cyclic loading. The Cellular column with eccentric bracing can resist the buckling load less than the plain-web column. The gable frame with web-tapered Cellular member has the load capacity and performance greater than other members in the study.
