Parameters Influencing Seismic Structural Collapse with Emphasis on Vertical Accelerations and the Possible Related Risks for New and Existing Structures in the Central and Eastern United States
… was primarily interested in the response of the structures between the earthquake intensities that have a 10 percent probability of occurring in 50 years (10/50) and 2 percent probability of occurring in 50 years (2/50). The results showed that all structures could be in danger of severe damage …

Vibration based assessment of Kalbaskraal rail bridge
The focus on the condition and performance of existing structures has increased due to the growing number of structures approaching or exceeding their design life. The challenges associated with the assessment of existing structures include deterioration, changes in loading conditions, changes in …

Heterogeneous Strain Distribution & the Effects of High Frequency Climate Change on the Evolution of Early-Stage Rift Systems: Case Studies from Lakes Tanganyika and Malawi (Nyasa), East Africa
… within the earth’s crust such as pre-existing structures. Such inhomogeneities from earlier rift or orogenic events can assist in weakening and stretching the earth’s crust. While extensional faulting drives continental rifting, changes in the relief of the landscape, erosion of …

Alamo Center: A mixed - use facility
… will involve the renovation of so.me of the existing structures, demolition of others, design of new linking structures, and the use of plazas and landscaping throughout the site in such a way that conflict will be minimal to the community and proper respect will be shown to the historical …

Back to school : the alternate ground of integration
… as well as a technical solution in appropriating existing structures. Its structural and spatial flexibility exploits the diverse shapes extant in existing structures, providing both visual and physical connections between workplace and learning, while fostering greater acceptance and knowledge of …

Dynamic response of URM buildings with flexible diaphragms
… need to evaluate the lateral resistance of existing structures. Unreinforced masonry (URM) structures are perceived to be seismically unsafe due to dramatic media coverage of these structures following earthquakes. However, well-built URM structures can possess substantial seismic …

Incipient continental rifting: insights from the Okavango Rift Zone, northwestern Botswana
… to map the distribution of rift and basement structures. The distribution of these structures provide useful insights into the early stages of continental rifting. The objectives of this study are (1) assessing the role of pre-existing structures on rift basin development, (2) characterizing …

Effects of Surface Condition and Environmental Exposure on the Bond between CFRP and Steel
As the existing steel infrastructure inevitably continues to age and deteriorate, engineers are increasingly looking for innovative and effective methods for repairing and maintaining existing structures. Structural steel components can degrade due to the surrounding environmental conditions, and …

Cladding Protection of Reinforced Concrete Structural Members against Blast Loading
With the increasing threat of explosions on infrastructures across the world, the protective techniques against blast loading on existing structures have become more and more significant. As an energy absorptive material, aluminium foam has been introduced to be a sacrificial cladding on …

A performance-based approach to retrofitting unreinforced masonry structures for seismic loads
The structural inadequacy of existing unreinforced masonry (URM) buildings to resist possible seismic loading is a serious problem in many parts of the United States, including the Northeast and Midwest. The fact that many of these buildings are deemed historic structures or house critical …
