Moments of the impulse response are widely used for interconnect delay analysis, from the explicit Elmore delay (the first moment of the impulse response) expression, to moment matching methods which creates reduced order trans-impedance and transfer function approximations. However, the Elmore delay is fast becoming ineffective for deep submicron technologies, and reduced order transfer functi...

Non-ductile reinforced concrete frames are commonly found in older buildings many parts of the world. These structures designed for gravity loads, have limited lateral strength and ductility, prone to excessive one-way movement soft-story mechanism. This paper focuses on retrofit an existing frame, using steel X-braces by direct internal connection method. The main purpose is analytical study g...

In the last few decades, a series of earthquakes were recorded which pointed out several deficiencies regarding ductile seismic response MR RC frame structures. Thus, research problem centres around failure mechanisms registered by structures, differ from general notions commonly found in current design standards and norms actions. these conditions, present paper—by using comparative methods—th...

In the first part of current study, effectiveness transversal cross-section reduction method for RC beams in marginal areas (by means mechanical drilling) was validated. The said “encourages” formation plastic hinges at beam ends and, same time, allows taking into account bending stiffness slabs, which is exerted upon beams. these conditions, second research study (i.e., manuscript) highlights ...

Numerical simulation models capable of predicting the nonlinear flexural behavior continuous reinforced concrete (RC) beams with corroded reinforcement were developed. Laboratory tests conducted to validate predictions numerical models. A parametric study was carried out examine effect varying location and severity corrosion on RC beams. The load capacity decreased linearly an increase in corro...
