After an earthquake, it is important to judge the safety of buildings and make efficient recovery plan. For that, necessary know quantitatively damage level limit buildings. An evaluation method residual seismic capacity described in Japanese Standard for Post-earthquake Damage Level Classification Buildings; however, does not consider difference deformation members such as walls frames (column...

In high speed digital integrated circuits, interconnects delay can be significant and should be included for accurate analysis. Delay analysis for interconnect has been done widely by using moments of the impulse response, 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 func...

Abstract This case study focuses on the evaluation of collapse rates various types reinforced concrete structures (residential and industrial) as observed from data collected in Romania after M w 7.4 Vrancea earthquake March 4, 1977. The results analyses show that largest were attributed to elevated silos water tanks. Moreover, majority collapsed tanks full at moment seismic event. Very small f...

Reinforced concrete (RC) structures built before the 1970 represent a large portion of existing European buildings stock. Their obsolescence in terms design criteria, materials, and functionality is becoming critical issue for guaranteeing adequate compliance with current structural codes. Recently, new jacketing system based on use high-performance fiber-reinforced (HPFRC) has been introduced ...

The flexural strengthening of reinforced concrete (RC) beams by bonding external composite materials has proved to be an effective and convenient technique. Several works, focus on mechanical behaviour continuous beam with two spans strengthened materials, were reported in literature. This paper presents the capacity RC three or repaired carbon glass fibre polymer (CFRP GFRP) sheets. Experiment...

This article examines experimentally and numerically the flexural performance of low-strength reinforced concrete (RC) beams strengthened using near-surface mounted (NSM) carbon fibre polymer (CFRP) rods. Five RC rectangular were tested in four-point bending until failure. Four these Bottom NSM (BNSM) or Side (SNSM) The results are discussed terms observed damage, load capacity, midspan deflect...

Reinforced concrete (RC) is a widely used construction material around the world. RC has many advantages in terms of structural stability. However, reinforcement requires extensive labour costs. Steel fibre reinforced (SFRC) been studied to replace steel bars structures over decades. most underground structures, such as tunnel lining, are usually designed using conventional for long-term stabil...

The double strap joint splicing of glass fiber reinforced polymer (GFRP) bars for concrete (RC) beams strengthening, applying the near surface mounting (NSM) method, has been proposed in paper. method consists application supplementary GFRP symmetrically positioned cut-off zone main reinforcement. performances this have experimentally tested most unfavorable case reinforcement maximal bending m...

In control engineering and structural dynamics, mathematical models such as the state-space representation, equation of motion, phase plane are matrix equations describing system equilibrium. This paper develops novel for linear/nonlinear dynamic analysis reinforced concrete (RC) buildings with cantilever elements lateral load resisting systems (e.g., RC shear wall, core). The offer a new appro...
