Experimental tests and constructive assessments are presented for a simple bamboo framed structure with innovative low-cost and low technology joints, specifically conceived for small buildings in developing countries. Two full scale one-storey bamboo frames have been designed by using the simplest joints solution among three different tested typologies. The entire building process is based on ...

Seismic behaviour of steel-concrete composite high-rise buildings, composed of external steel frames (SF) and internal concrete tube (CT), with rectangular plan is investigated in this paper. A macro-element based model is established for seismic analysis of composite high-rise buildings aiming at predicting their global responses under earthquakes. By employing this macro-element based model, ...

The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...

The principal and school leadership team have established and are driving a strong, positive learning culture, grounded in evidence from research and practice. Explicit and clear school-wide expectations have been established with families, teachers, and students. Strong procedures are in place to encourage a school-wide, shared responsibility for student management, and to encourage the develo...

Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...

Diving into parenthood is never easy, but for common murres (Uria aalge) some positively prudent parenting is required. These birds have to decide whether they care more about the chicks they have got or about having additional chicks in the future. Anne Storey and her colleagues were able to measure the physiological tell-tale signs of this balancing act both when food is scarce and when food ...

High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...
