Steel frames are very ef cient in resisting forces generated from ground motion because of their ability to dissipate seismic energy through large inelastic deformation and damping. Therefore steel is often used for buildings in seismically active regions. Furthermore nowadays construction of light buildings is common, so it is important to study the behaviour of high-raised building under self-weight and dynamic loads. The design of steel structures subjected to natural hazards such as earthquakes demands safety of structures which is governed by the fundamental frequency and the magnitude...

Nowadays, concrete filled steel tube columns (CFST) are commonly used in composite construction. However, not many research studies are found on the application of a CFST together with a composite beam. This book is carried out to study the behaviour of a composite connections which include a combination of a CFST and a composite beam. In this book, the composite connections was connected via two different types of innovative connections; blind bolt and thorough bolts and combined with the contribution of reinforcement bars in a slab to the tensile strength. Three dimensional (3-D)...
