plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...
The proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(X/H)0.5 for low-rise and mid-rise buildings, 2- Sin(ΠX/H) for high-rise buildings. These two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. The assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
This paper aims to investigate the energy saving and carbon reduction performance of cross-laminated timber residential buildings in the severe cold region of China through a computational simulation approach. The authors selected Harbin as the simulation environment, designed reference residential buildings with different storeys which were constructed using reinforced concrete (RC) and cross-...
The aim of this study is to compare the seismic response reinforced concrete (RC) symmetric buildings, with a varied number stories, strengthening three types passive energy dissipation systems, as tuned mass dampers, viscous and friction dampers. paper presents an overview design optimization object minimizing certain functions: (i) maximum displacement at top structures, (ii) base shear loads...
The paper reports the results of a joint project on evolutionary design of reinforced concrete structures in tall buildings. It has been conducted at the Center for Concrete Structures at the Darmstadt University of Technology in Germany and in the School of Information Technology and Engineering at George Mason University. Its ultimate objective is to revolutionize design of both steel and con...
One of the main tasks of engineers is to design structural systems light and economic as possible, yet resistant enough to withstand all possible loads arising during their service life and to absorb the induced seismic energy in a controlled and predictable fashion. The traditional trial-and-error design approach is not capable to determine an economical design satisfying also the code require...
High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...
(RCS) frames which are systems that dwell of concrete columns and steel beams , by optimizing the act of compressive strength of concrete and bending strength of steel due to not only a decrease in building weight in comparison to concrete structures but also having a better action in long spans frames . In this paper for analysis RCS behavior, a category of nonlinear Push Over analyses were ...
