Effective Rigidity of Reinforced Concrete Elements in Seismic Analysis and Design

Seismic analysis and design of reinforced concrete structures are performed based on linear response, however it is universally accepted that under severe earthquakes inelastic response and cracking is accepted. Therefore element properties should reflect this condition and inertias of beams and columns should be reduced accordingly. Several procedures are suggested to considered effective rigi...

Earthquake Resistant Design of Reinforced Concrete Buildings

This paper briefly reviews the development of earthquake resistant design of buildings. The state-of-the-art of seismic design is discussed from the viewpoint of the performance criteria of buildings. These are (a) serviceability from frequent minor-intensity earthquake motions, (b) repairability from an infrequent but major-intensity earthquake motion, and (c) life safety from the maximum poss...

Optimizing of Steel Fiber Reinforced Concrete Mix Design

Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translat...

Adaptive Finite Elements for Reinforced Concrete Framed Structures

Abstract. This work focuses on the modelling of nonlinear response of reinforced concrete structures by means of the finite element method. A new technique which employs a variable mesh in order to reduce the computational cost of classical approaches is presented. For some piecewise linear constitutive models which are widely employed for the modelling of reinforced concrete, some properties o...
