A method to predict the column size for displacement based design of reinforced concrete frame buildings with higher target inter storey drift is reported here. The column depth derived from empirical relation as a function of given beam section, target inter-story drift, building plan features and common displacement based design parameters is used. Regarding the high drift requirement, a mini...

The aim of this paper is to report on an experimental study about Turkish Earthquake Code on suggested strengthening method. The proposed method uses existing brick infill walls and the strengthening is done with the application of external mesh reinforcement and plaster. 5 nonductile 1/2 scaled, one bay, two storey RC specimens were tested under a reversed cyclic loading. The first two specime...

SPOT panchromatic imagery of Beijing has been studied to capture the unique spatial pattern of the city. Texture analysis, which reveals spatial variations, was adopted to interpret the urban spatial patterns. Statistical and structural texture features were extracted from the SPOT image and evaluated for their capability of detailed mapping of urban structures. Supervised image classifications...

Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approach is employed which is a simple and efficient method. At first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

Academic governance is an important dimension of institutional self-governance. This paper reports on the findings of a new study of university senates (academic councils) in Canadian universities in order to analyze changes in structure and in senate members’ perceptions of the structure and role of senates over the last decade. Following the basic design of a similar study in 2000, this study...

There is an increasing amount of research focussing on the transition to adulthood, a stage of the life cycle where young people face demanding life decisions, including completion of education, finding stable employment, and establishing their household and family. Whereas there is a well-developed literature on poverty among households in general, very little research has focused on poverty a...

Midto high-rise buildings are often braced by slender reinforced concrete (RC) walls, which are coupled by RC floor diaphragms. In design it is typically assumed that the walls act independently and the design base shear demand is computed neglecting any compatibility forces between the walls. Pushover analysis of systems comprising walls of different lengths have, however, shown that large com...

Traditional modeling approaches support a limited set of instantiation levels (typically one for classes and another adjacent one for objects). Multi-level modeling approaches on the other hand have no such limit to the number of levels. As a consequence, an arbitrary number of levels may be used to define models, and the distinction between class and instance is redefined. The paper summarizes...
