Recently, steel structures have been accounted for a large percentage of the buildings due to their advantages such as higher execution speed and easier construction. In steel structures, welded joints are commonly used and their quality plays a key role in stability of buildings under applied loads. Hence, to increase resiliency of welded steel structures against natural hazards, welded joints...

in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...

Multi-processor DSPs have become the platform of choice for wireless infrastructure. This trend presents an opportunity to enable faster and wider scale deployment of signal processing applications at scale. However, achieving the hardware-like performance required by signal processing applications requires interacting with bare metal features on the DSP. This makes it challenging to build modu...

A short review for design consideration of two common materials used in facade and curtain walling is presented. The characteristics of light-weight facade enveloping a building are different from the conventional steel or concrete structures. Glass cannot crack like concrete and it is much more brittle than steel. Aluminum involves many buckling modes similar to but more common than steel. Owi...

There are over six hundred thousand bridges in the U.S. which require great amount of human effort along with expensive and specialized equipment for maintenance. Current bridge inspections are manually performed by inspectors which are inefficient and unsafe. This paper presents visual and three dimensional (3D) structure inspection for steel bridges and steel structures using the developed cl...

The Cambridge Handbooks on Construction Robotics series focuses on the implementation of automation and robot technology to renew the construction industry and to arrest its declining productivity. The series is intended to give professionals, researchers, lecturers, and students basic conceptual and technical skills and implementation strategies to manage, research, or teach the implementation...
