Physical activity is associated with better health; however, the optimal intensity of activity remains unclear. A total of 13,485 men (mean age, 57.5 years) from the Harvard Alumni Health Study reported their walking, stair climbing, and sports/recreation in 1977. Between 1977 and 1992, 2,539 died. After adjusting for the different activity components, distance walked and storeys climbed indepe...

Forest ecosystems face challenges of climate change and the pressure economic activity on biodiversity. As European policies turn into Green Deal, ecological forestry systems, which aim to increase or at least not reduce biodiversity while maintaining high forest productivity, are becoming particularly relevant. This study examines distribution regularities lower storeys main tree species in fe...

The article considers the typology of housing stock mass building series on example city Belgorod. Data its classifications are presented: according to form ownership, purpose use, planning structure, design features. Analyzed historical archival data relating development in main stages residential territories Belgorod singled out: from 1945 1964. - period restoration after hostilities and begi...

This paper presents numerical simulations of multi-storey reinforced concrete frames under progressive collapse scenarios. Reinforced with different storeys are modelled using DIANA. The load resistance and failure mode obtained from the simulation. Variations in axial force bending moment at beam end also determined analysed to shed light on transfer mechanism. Numerical results show that sing...

This research was designed to determine the optimum percentage and configuration of rhombus opening on shear wall tall building. A residential building 12-storeys having base size 20m × 10m with height floor 3m analyzed. In this paper, percentages 12%, 24%, 36%, 42%, 54% concentric in a buildings were modeled. The effect lateral displacement, shear, stress at determined. It found that 12% has l...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

The underlying cause of the problem with parking is imbalance between demand and supply in key areas where for high, but limited due to excessive land prices. Newly-developed automated multi-storey facilities are able automatically pick up place cars on different storeys, minimal requirements space. In paper we concentrate Automated Parking Systems their malfunction rate. Specifically, analyzed...
