in this paper a new method based on strut-and-tie model (stm) is proposed to determine the shear capacity of simply supported rc deep beams and an efficiency factor for concrete with considering the effect of web reinforcements. it is assumed that, the total carried shear force by rc deep beam provided by two independent resistance, namely diagonal concrete strut due to strut-and-tie mechanism ...

Resistance in the workplace, by nurses, has not been extensively studied from a sociological perspective. In this paper, nurses' resistance to the implementation and use of computer systems is described and analysed, on the basis of semistructured interviews with 31 nurses in three UK NHS hospitals. While the resistance was not "successful", in that it did not prevent the implementation of the ...

The paper discusses the results of an experimental investigation carried out on reinforced concrete (RC) beams strengthened in shear by externally bonded fiber reinforced plastic (FRP) sheets. The study is devoted to analyze the role that the transverse steel reinforcement and the beam slenderness ratio could play on the resistant mechanism of RC beams strengthened in shear by FRP composites. T...

The robustness of large scale critical infrastructures, which can be modeled as complex networks, is of great significance. One of the most important means to enhance robustness is to optimize the allocation of resources. Traditional allocation of resources is mainly based on the topology information, which is neither realistic nor systematic. In this paper, we try to build a framework for sear...
