In steel modular buildings, both inter- and intra-module connections can attract bending moment under the action of lateral loads. The is distributed in accordance with relative stiffness ratios among structural components hence should have sufficient flexural resistance to connecting members be classified as a rigid connection. Typically, (beam-column joints within module) are designed full-st...

Origami-inspired foldable structures have seen much recent interest for applications in which transportability or rapid construction are primary design drivers, for example emergency shelters and temporary staging structures. This paper proposes a new type of a structural module that can be manually folded from flat steel sheet into a novel self-braced triangular structural section. Simple geom...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

Braced piers of steel truss bridges having braces with latticed built-up cross-sections may su er significant damage during earthquakes due to the buckling, rapid strength degradation, and fracture of the braces. One retro t alternative for such a bridge pier is to supplement the existing structural system with a system of energy dissipation devices (or structural fuses) that will yield and dis...

In recent years, seismic design of structures has been undergoing significant changes due to increasing demand for optimization and minimizing the level of damage and reducing the cost of structural repairs. Development of analytical methods and remarkable improvements of computer performance have been among the factors which influenced the design of structures. A lot of research has been condu...

Conventional concentrically-braced frame (CBF) systems have limited drift capacity before brace buckling and related damage leads to deterioration in strength and stiffness. Self-centering concentrically-braced frame (SC-CBF) systems have been developed to increase drift capacity prior to initiation of damage and minimize residual drift. SC-CBFs differ from conventional CBFs in that the SC-CBF ...

Current innovative lateral load carrying systems for tall buildings are those in which the lateral drift is limited to an allowable value without considerable influence on economy. This aim is achieved by using special systems capable of using maximum stiffness and strength capacity of individual structural elements. An effective structural solution in this respect is the use of outrigger brace...

In recent years, the devastating earthquakes that occurred in many parts of world have made it even more important design earthquake-resistant structures and earthquake performance assessment existing structures. When innovative systems are examined building design, is seen depending on developments performance-based designs come to fore addition force-based design. This paper provides a new me...

Passively damped bracing systems in steel frames, in which the conventional materials of the joint are replaced by high damping viscoelastic materials, have the potential of being effective practical means for passive vibration control of dynamically loaded civil engineering structures. However, this potential can be realized only if the associated structural penalties are reduced within accept...
