1. ABSTRACT Devices which can add damping and strengthen structural systems, without changes to the existing components, were found recently extremely useful in retrofitting lightly reinforced frames and other structures. Some damping devices were developed purposely for building structures, however, many more were adapted from use in other industries such as the military and aerospace. Damping...

High-resolution seismic reflection has been used successfully to characterize material and investigate a variety of problems associated with earthen dams and abutments. Limitations and challenges of seismic reflection when interrogating these structures and lithologies are nontrivial and require very critical thinking. Seismic reflection has proved an effective tool for mapping confining units ...

This paper presents an optimization process for the design of a novel synergetic seismic and energy retrofitting strategy that combines favorable mechanical properties timber attractive thermal insulation bio-based materials. The method, defined as Strong Thermal Seismic Backs (STSB), comprises attachment frames panels on vertical envelope facade walls existing masonry buildings, thus improving...

Masonry buildings built in Italy the 60 s and 70 of last century frequently require energy seismic renovation. To this end, use a retrofitting technique based on multilayer coating may be applied building façades order to improve its performances, leading partial or total fulfilment structural code provisions. The consists layer Steel Fiber Reinforced Mortar combined with thermal insulation mat...

Due to the complexity of construction environment and retrofitting methods, it is difficult achieve expected effect. Therefore, effective seismic training a necessary way ensure workers acquire enough professional knowledge, skills safe behaviors, which are critical retrofitting. Mixed reality has huge potential in training. This paper conducts fuzzy comprehensive evaluation MR system research ...

Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop the seismic design procedures to not only satisfy life safety criteria but also lead to more economical buildings. One of these modern methods of improving seismic performa...
