The role of softening in the numerical analysis of RC framed structures
free download

Abstract. Reinforced Concrete beams with tension and compression softening material constitutive laws are studied. Energy-based and non-local regularisation techniques are presented and applied to 3 RC element. The element characteristics (sectional tangent

Nonlinear seismic analysis to evaluate the effectiveness of damped braces designed for retrofitting rc framed structures
free download

Abstract:The supplementary energy dissipation represents an efficient technique for the seismic protection of structural systems. In the last few decades several applications have been used in many countries, adopting damping systems with different characteristics,

Design of hysteretic damped braces to improve the seismic performance of steel and rc framed structures
free download

Displacement-Based Design (DBD) procedure is adopted for the retrofit of framed structures by inserting hysteretic damped braces (HYDBs) in order to attain, for a specific level of seismic intensity, a designated performance level. To check the reliability

Base-isolation techniques for the seismic protection of rc framed structures subjected to near-fault ground motions
free download

SUMMARY The main objective of this work is to compare different base-isolation techniques, in order to evaluate their effects on the structural response and applicability limits under near-fault earthquakes. In particular, high-damping-laminated-rubber

The influence of the seismic design on the progressive collapse resistance of mid-rise RC framed structures
free download

Abstract In this study the influence of the seismic design to better resist progressive collapse of mid-rise RC framed structures is investigated. A ten-storey building is designed for three distinct seismic areas from

Seismic assessment of existing rc framed structures with in-plan irregularity by nonlinear static methods
free download

Abstract. This paper evaluates the effectiveness of three nonlinear static methods for the prediction of the dynamic response of in-plan irregular buildings. The methods considered are the method suggested in Eurocode 8, a method previously proposed by some of the

Retrofitting of RC framed structures through SMA-based energy dissipating and re-centering braces
free download

ABSTRACT An extensive program of shaking table tests on scale three-dimensional R/C frames, designed without any seismic provision, was carried out by DiSGG with the earthquake platform of the Portuguese National Laboratory of Civil Engineering (LNEC) at

Development of a fibre flexure-shear model for seismic analysis of RC framed structures
free download

ABSTRACT Currently the accurate simulation of the behavior of reinforced concrete (RC) structures subjected to strong motion is still a challenging and open problem. In particular, the determination of the shear strength and deformation response is still far from reaching

Progressive collapse resistance of low-rise RC framed structures from seismic areas
free download

ABSTRACT: In this study the inherent capacity of seismically designed RC framed structures to resist progressive collapse is investigated. A three-storey building is designed for a low and moderate seismic area from Romania. As recommended by the GSA (2003)

Progressive Collapse Potential of Seismically Designed RC Framed Structures Subjected to Column Removal
free download

Summary: In this study the risk/potential for progressive collapse of seismically designed RC framed structures under abnormal loads (missing column scenarios) is investigated. A ten- storey building is designed for a low and high seismic area from Romania. As

Evaluation of second order effects on the seismic performance of RC framed structures: a fragility analysis
free download

SUMMARY This paper is aimed at probabilistic evaluation of second order effects (P- effects) on the inelastic response of RC framed structures subjected to seismic excitations. To this purpose, the study focuses on the seismic performance of a double span, 8-story

Behavior of RC Framed Structures Designed According To Iranian Seismic Code Due To Near-Fault Earthquakes
free download

ABSTRACT In this paper six-and three-storey RC plane frames, representing medium and low-rise symmetric framed buildings were designed according to Iranian seismic code (2800) with reference to ground profile type I (rock site) in a high-risk seismic region.

CYCLIC NONLINEAR BEHAVIOUR OF RC FRAMED STRUCTURES ACCOUNTIG FOR FLEXURE-SHEAR INTERACTION
free download

ABSTRACT: Fibre beam-column elements thus far proved to be very accurate in the simulation of flexure dominated behaviour of reinforced concrete (RC) frames. However, when the shear span of the frame elements is small, the shear behaviour plays an

Influence of Masonry Infill Walls on Seismic Performance of RC Framed Structures-A Comparison of AAC and Conventional Brick Infill
free download

Abstract-In general design practices in India, the strength and stiffness of infill walls are ignored with the assumption of conservative design. In actual, infill walls add considerably to the strength and rigidity of the structures and their negligence will cause failure of many of

Effect of Vertical Irregularities of RC Framed Structures by Using Non-Linear Static Analysis
free download

Abstract: Major structural collapses occur when a building is under the action of Dynamic Loads which includes both Earthquake and Wind loads. In these modern days, most of the structures are involved with architectural importance and it is highly impossible to plan

EFFECTIVENESS OF MULTIPLE TSWDs FOR SEISMIC RESPONSE CONTROL OF MASONRY-INFILLED RC FRAMED STRUCTURES
free download

ABSTRACT An existing masonry-infilled RC framed structure can be retrofitted for improved performance under earthquake loading by the structural response control methodology using tuned sloshing water dampers (TSWDs). The retrofitting may be accomplished by

NUMERICAL METHODS IN PROGRESSIVE COLLAPSE ASSESSMENT OF RC FRAMED STRUCTURES: FEM vs. AEM
free download

ABSTRACT Progressive collapse is, according to GSA (2003), a situation where local failure of a primary structural component leads to the collapse of adjoining members which, in turn, leads to additional collapse. Since the experimental studies are costly and difficult to

INELASTIC SEISMIC ANALYSIS OF RC FRAMED STRUCTURES CONSIDERING JOINT DISTORTION
free download

ABSTRACT Seismic performance of reinforced concrete (RC) framed structure can be assessed with various analytical tools that may broadly be classified as linear elastic procedures and non-linear or inelastic analysis procedures. Since the reinforced concrete

Abstract. The paper approaches the shakedown optimal design of reinforced concrete (RC) structures, subjected to variable and repeated external quasi-static actions which may generate the well-known shakedown or adaptation phenomenon, when constraints are

free download

Abstract Spectra based multimodal adaptive pushover analysis considers higher modes of vibration and combines them using SRSS rule and scale factors. Damage index for the structures are calculated to evaluate the degree of damage occurred after a seismic event.
