Abstract : In modern multistorey building construction, irregularities like the soft storey, vertical and plan irregularities, floating columns etc are very common. Building with an open ground storey for parking is a common feature that results in floating columns. Floating columns provide column free space and a good aesthetic architectural view of the building. floating column means the end of any vertical element that rests on the beam which leads to discontinuity of columns such that the path of load distribution in multi-storey buildings is disturbed. The use of a floating column also te

This paper presents analyses of the seismic responses of two reinforced concrete buildings monitored for a period of more than two years.

Both buildings are part of the same large complex but are seismically separated from the rest of it. Statistical analysis of the relationships between maximum free field accelerations and responses at different points on the buildings was conducted and demonstrated strong correlation between

A multi-storey building is habitually modelled as a frame structure which neglects the shear wall/slab openings along with the inclusion of staircases. Furthermore, the structural strength provided by shear walls and slabs is not precisely incorporated. With increasing building height, the effect of lateral loads on a high-rise structure increases substantially. Inclusion of shear walls and slabs with the frame leads to improved lateral stiffness. Besides, their openings may play imperative role in the structural behaviour of such buildings. In this study, 61 multi-storey building configuratio

Abstract:
The paper is devoted to the problem of arrangement of the city's ecosystem by the architectural and design tools. The contradictions and conditions of joint habitation of people and street animals (cats) in the urban environment are revealed. The initial potential capacity of different types of urban environment (beaches, a traditional Odessa courtyard, public parks and squares, modern multi-storey buildings) in the formation of a harmonized, conflict-free interaction between people and animals have been investigated. The sketches of the search for the artistic appearance of cat settlements (s

Calculation of coverage using the Free Space Loss (FSL) method and measurement with a walk test. Calculation of coverage with the DCS1800 and U2100 networks uses the FSL method to determine the coverage distance per omni ceiling antenna. The result is the farthest distance is 24 meters and the closest distance is 4 meters and the average distance per omni ceiling antenna is 8 meters. As for the results of the walk test on the DCS1800 network, very good results were obta

An analytical investigation of the P-delta effects in medium height steel moment resisting frames excited by selected earthquake motions is reported.
 The frames with various design drifts and fundamental natural periods of free vibration were designed according to the loadings provisions for New Zealand's highest seismic risk zone (Wellington) of the Draft Code of Practice for General Structural Design and Design Loading for Buildings, DZ4203 [10] as issued as a "Draft for Comment" in May 1986.

Abstract:
Base isolation incorporation has moved towards a popular technology in the seismic vulnerable regions. The system mitigates lateral action of tremor hazard providing flexibility of structures. Implementing base isolation on buildings in the soil and seismic condition of medium risk seismicity is currently an important issue. A thorough investigation is of burning need for buildings to be incorporated with base isolator and to carry out dynamic analysis. The study provides incorporation of rubber-steel bearings and focuses on the structural changes. Designs of base isolation bearings are perfor

Abstract:
This study focuses on two little-known mid-nineteenth-century pamphlets which proposed radical changes to the ways in which large public and administrative buildings were planned. Although one author went to some lengths to remain anonymous, the other was soon to become recognized and respected as a major critic and historian of architecture. These ideas were thus by no means the fantasies of peripheral dreamers. Indeed, they were possible, practical solutions to current problems which used both proven and emerging technologies. Both authors advocated deep, top-lit, single-storey, ‘universal’,

The paper is dedicated to waste processing management in waste processing technology. Processing of scrap concrete waste, similar in composition and condition to traditional raw materials, is economically and ecologically feasible. Secondary crushed stone obtained by crushing scrap of reinforced concrete panels in demolished five-storey apartment blocks of the first phase was studied. It is shown that concrete with scrap concrete waste shows strength properties similar to primary concrete and helps organize waste-free production. The methods of recycled waste usage, especially usage of seconda

Bracing system is one of the structural system which forms an integral part of the frame. Steel bracings have been used extensively as a structural system to resist seismic loads in the recent times due to their passive energy dissipation property. Steel bracing being economical and easy to erect assists to enhance the strength and retrofitting properties of a structure and their effective performance in controlling seismic effects on the structures during earthquake. In the present study the effect of soil structure interaction (SSI) on multi-storied vertically irregular RC buildings on a hor

There is an old Danish fable that says that the Devil was watching when God created the earth, and that, as the creation progressed, he became increasingly agitated over the wondrous achievements he was made to witness. At the end of it all, the Devil turned to God, and said, ‘Now, watch this.’ He created Iceland. It’s a vision of the country that resembles my own. I have always thought of Iceland as the island apart. The place that came last in the earth’s construction, whoever the engineer, and so remains forever distant. Perhaps that’s because, for me, Iceland is a home far from home. It is
