It has recently been shown that the ever-increasing complexity and inability of methods used for the design of reinforced concrete (RC) structures to consistently safeguard against brittle types of...

Reinforced concrete design is in a state of perpetual revision of ever-increasing complexity. But it has yet to achieve the aim of preventing the recurrence of unexpected types of brittle failure. ...

In spite of the considerable number of reinforced-concrete structures invariably suffering earthquake damage in the regions of points of contraflexure of their beam or column elements, research on the subject to date has been sparse. This work discusses the causes of such damage and proposes a simple design method that does not require calibration through the use of experimental data. A comparison of the proposed method's predictions with experimental information and the predictions of typical c...

In the present study a shear wall of 1.7 m length, 1.7 m height and 0.15 m width was designed, in compliance with the Greek Code for Reinforced Concrete (GCRC) and the Compressive Force Path method (CFP). The 1.7 m long wall, designed according to the current GCRC was constructed and tested under cyclic loading, applied in two phases. Under the first one, the specimen reached a displacement of 38.5 mm and a load of 710 kN and under the second one, the maximum displacement was 72 mm and the load ...
The work presented concerns an investigation of the effect of bond between concrete and longitudinal reinforcement on the behaviour of reinforced concrete beams, without transverse reinforcement, subjected to transverse loading combined with an axial force in selected cases. The results showed that the development of bond anywhere within the shear span inevitably leads to inclined cracking, which is the cause of ‘shear' failure. Similarly, eliminating bond throughout the beam's span was also fou...

The application of the compressive force path method for the design of earthquake-resistant reinforced concrete structural walls with a shear span-to-depth ratio larger than 2.5 has been shown by experiment to lead to a significant reduction of the code specified transverse reinforcement within the critical lengths without compromising the code requirements for structural performance. The present work complements these findings with experimental results obtained from tests on structural walls wi...

The work presented is concerned with the application of the compressive force path (CFP) method for the design of earthquake resistant reinforced concrete structural walls. It is based on a comparative study of the results obtained from tests on structural walls under cyclic loading mimicking seismic action. Of the walls tested, half have been designed in accordance with the CFP method and the remainder in accordance with the provisions of euro-codes 2 and 8. The results obtained show that both ...

Since the mid-eighties, there has been an increasing amount of experimental evidence which shows that many of the concepts underlying current-code provisions for the design of reinforced-concrete (RC) structures are in conflict with fundamental properties of concrete at both the material and the structure levels.
