Walking-induced vibration control in multifamily timber buildings: Analysis of floor configurations and support conditions using classical vibration theory

Practical combinations of floor configurations and support conditions are studied for the development of a lightweight timber building method that is suitable for multi-family residential buildings. Classical vibration theory forms the base for a methodology that is developed to assess transmittance of vibrations to adjoining floor fields....

Characterisation of recycled concrete aggregates from construction and demolition wastes

Construction and demolition waste form a significant problem in terms of environmental pollution and material depletion. Concrete, as part of construction and demolition waste, is already responsible for 9% of the total anthropogenic carbon dioxide emissions. Consequently, it is important to alleviate the environmental stress of concrete by...

Damage to Masonry Houses due to a Riverine Dyke Breach: A hydraulic and structural approach

The Netherlands has always been in close proximity to water, whether its rivers or the sea. This proximity to water and the need for land to settle and farm, led to vast amounts of land reclamation by constructing dykes along the water features to prevent flooding of the new earned land. This newly reclaimed land started to subside over the...

Verification and optimization of nonlinear shell buckling formula of thin-shell structures

Shell is a popular form of structures as it can withstand relative large load with small thickness, which satisfies the aesthetic preference. Due to the curvatures of shell structures, shell can carry the distributed load as membrane forces instead of bending moments. Due to the small thickness, shell structures are highly sensitive to...

Quantifying the influence of membrane forces, curvature, and imperfections on the nonlinear buckling load of thin-shells

Shells tend to be thin because their curvature enables them to carry distributed loads as membrane forces. The property of thinness stems from shells’ capacity to store membrane strain energy without much deformation. As a result, buckling failures often govern the design of shell structures. These buckling failures usually start locally, at a...

Dynamic Stability of Tunnel Elements During Immersion and Transportation

Immersed tunnel elements are prefabricated in the construction yard and then transported to the construction site to be integrated into the tunnel. During the transportation and immersion, the floating tunnel element is connected via cables to the immersion barges/pontoons. In this study, the hydrodynamical behavior of a floating tunnel element...

Seismic assessment of a detached masonry building using non-linear analyses

Masonry is one of the oldest and popular building materials used world over. The constituent materials are readily available and hence are cheap in most areas. So it serves as an economically viable building material. Though, its load bearing capacity under compression is high, it does not perform well under tensile forces, cyclic and lateral...
