As one of the serviceability limit states of structural design, excessive vibration has attracted more attention in recent years, with the design trend moving toward lighter and more slender structures. Footfall vibration contains high uncertainties in nature, with significant variations in walker weight, walking speeds, and dynamic load factor. Si...

Existing-building seismic performance and collapse assessment methodologies used today are often either simplified screening-level procedures constrained by limited information and level of detail, or highly sophisticated numerical modeling procedures constrained by the computational costs of conducting comprehensive probabilistic analysis. In this...

Structures of various function can be affected by human induced vibration in many ways. Depending on the type of the structure, the load, the structural response, and the serviceability criteria to be met vary and may not be clearly defined. There are several guidance documents covering the evaluation of the footfall aspect of human induced vibrati...

This work fully investigates a specific timber joinery connection via experimental, analytical, and numerical methods. The selected joint is the Nuki joint: a mortised column with through-beam tenon. The experimental approach takes advantage of digital fabrication to reduce variations introduced by hand fabrication while the analytical approach bui...

This paper investigates the structural performance of traditional moment-resisting interlocking timber joints for modern building construction. Gradually improved over generations, traditional Japanese and Chinese interlocking connections have proven structural integrity. In this paper, first, an overview of the development of historical Japanese a...
