To assess the performance criteria of the reinforced-concrete, five-storey residential buildings common in Iran, an &#10experimental study in the structural laboratory of the University of Tehran has been conducted. The test program includes cyclic and monotonic load tests of six beams that represent three-to-five storey buildings with rigid frame structures. Using definitions given in FEMA-356...

This paper presents current design approaches found in the U.S. and European building codes and standards for the prevention of progressive collapse due to abnormal loading. Because the definition of abnormal loading is not well established, design provisions are based on an approach that protects buildings by means of strength, ductility and redundancy. The effectiveness of seismic detailing o...

Abstract Blood sampling typically involves puncturing a superficial vein with needle and then creating vacuum (e. g., syringe) to transfer the blood from venous system collection container. In some cases, walls collapse due excessive generated. this work, device is presented that prevents can be combined any available on market. The mechanism of preventing based tubular segment interconnected b...
