In two and almost a half years of writing this column my mum, Vesna Andrijević-Matovac, and I, Nika Matovac, shared with you a true and very intimate story of a woman with breast cancer and her daughter. In these columns, you have witnessed our great moments, sad moments, and devastating moments, you have been a part of our life. Now, as everything has its beginning and its end, it is time to s...

This paper presents a simple displacement-based seismic design method for RC frames with steel damper column. As numerical example, two 10-story frame building models are shown. The results of nonlinear time-history analysis show that the peak displacement at equivalent height is close to target displacement. strength demand beam ends connected columns, and beam-damper column joints, calculated...

‘‘Daddy, tell me a story. A good one.’’ An engineer pauses at the request. We know how to measure and build many things. But imagining, crafting, and telling a story? That is hard. If you are building or researching any aspect of multimedia, however, then you should be thinking about how your work helps both you and the user experience a story. Telling stories is an important part of how we com...

Mid-story pin column system has been proposed to realize beam yielding mechanism of a steel moment-resisting frame. In this system, connection is applied inbetween the upper and lower RC extended from base control moment demands on both ends first story column. An exposed-type adopted as connected by single anchor bolt. Static cyclic horizontal loading tests partial frame consisting second floo...

A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...

Dantzig-Wolfe decomposition and column generation, devised for linear programs, is a success story in large scale integer programming. We outline and relate the approaches, and survey mainly recent contributions, not yet found in textbooks. We emphasize the growing understanding of the dual point of view, which has brought considerable progress to the column generation theory and practice. It s...

Abstract Earthquake is one of the horrible natural disasters. With considerable developments in constructional science, experts have been able to find out factor forces that cause earthquakes damage and destructions different types buildings, including residential commercial caused by earthquake are high importance need be considered. The multi-story buildings usually weak points building, whic...
