Nowadays, due to environmental changes, the condition of buildings can be in danger. In order protect performance existing buildings, it is important investigate seismic behaviour building structure subjected earthquake excitation. addition, study advanced level ductile design recommended by current codes. immediate future, lateral load resistance needs evaluated precisely. For purpose analyzin...

the purpose of this study is to determine the effect of vierendeel panel width and vertical truss spacing ratio in an inelastic behavior of the stf system due to earthquake loads. the stf system is applied to a six-storey building that serves as apartments [2]. the stf system is used in the building in the transverse direction (n-s direction), while in the longitudinal direction (w-e direction)...

The present paper proposes the use of stepped cross section devices on steel frames aiming at reproducing a pre-established target push-over curve. To this aim Limited Resistance Plastic Device (LRPD) to be inserted along selected structural members is proposed. following two main specific features for LRPD are required: any elastic flexural stiffness variation original member must avoided; an ...

AbstractExposed column base plate (ECBP) connections are commonly used in steel moment resisting frames. Current approaches for their design well-established from a mechanistic standpoint. Howe...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...
