according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

Abstract Concrete indeterminate flexural members represented by continuous beams reinforced with both fiber-reinforced polymers and steel bars in a way that allows for moment redistribution at failure are analyzed. The efficiency of introducing the critical sections where plastic hinges likely to form is evaluated terms reliability. Monte Carlo simulation concept comparative reliability employe...

the dial by two screws, but in the faulty vaporizer one had fallen out, into the top of the casing. With the cam loose, it was possible to turn the dial a few degrees clockwise beyond the OFF position, when a strong smell of enflurane was noticed in the fresh gas flow. Anaesthetists should be aware that unless the OFF mark on the concentration setting dial coincides with the datum mark, then th...

Numerical simulations have been widely used to study the inelastic response of reinforced concrete structures under earthquake loading. Yet, due to the complex nature of structural inelastic behavior, experimental results are often required to verify the efficiency of applied numerical schemes. In this paper, experimental results of bare reinforced concrete frame models are employed to validate...

This paper presents a new design of a low cost, unlubricated, self-deploying, self-locking hinge whose properties can be easily modified to meet different requirements. A particular implementation is considered, providing a hinge that is 135 mm long, 30 mm high and 45 mm wide, with a deployment moment varying between 0.1 and 0.3 Nm and a locking moment of 13 Nm. Stiffness tests have been carrie...

As an ancient paper craft originating from Japan, origami has been naturally embedded and contextualized in a variety of applications in the fields of mathematics, engineering, food packaging, and biological design. The computational and manufacturing capabilities today urge us to develop significantly new forms of folding as well as different materials for folding. In this paper, by allowing l...
