Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...

The roof–column structural system is utilized for many engineering and architectural applications due to its efficiency. However, it typically requires column locations be predetermined, involves a tedious trial-and-error adjusting process fulfil both requirements. Finding efficient distributions with the aid of computational methods, such as optimization, an ongoing challenge. Existing methods...

Aiming at the construction of infill wall structural column are often used in artificial layer pouring method and top pouring back method, to improve the structure of wall column concrete pouring process, puts forward a new type of structural column concrete pouring machine. The application of this equipment, process worker can finish pouring filled wall structure column and tap filled wall str...

We give simple necessary and sufficient conditions for the existence of a zero-one matrix with given row and column sums and at most one structural zero in each row and column. © 2006 Elsevier B.V. All rights reserved.
