Failure of some elements in the structure can play triggering role for beginning of collapse progression. The critical element is the structural element that when it fails, leads to progressive collapse. To find the critical element of the structure, sensitivity analysis should be done. But there are not specific structural criteria for using in sensitivity analysis. In this paper following GSA, UFC 4-023-03 and ASCE guidelines, sensitivity analysis has been modified and applied to find the critical element of a major number of reinforced concrete structures. 1080 3D nonlinear pushdown analyses were done and the results showed that the place of the critical elements differs in different stories and different plan shapes of high rise structures. In the structures with high aspect ratio in height, the critical element of the whole structure is located in the story of 2/3 height of the structure. When the aspect ratio of the structure in plan increases, sensitivity of the columns in the long dimension of the structure become closer to each other.

<p>There is little doubt New Zealand is in the midst of a housing crisis. A growing population and a construction industry unable to meet demand makes housing supply an ongoing issue. The most sustainable way to meet housing demand is to increase density within existing city limits; however, growth in this way is problematic due to the stigma surrounding high-density housing. High-rise apartment living in particular is seen as undesirable to most New Zealanders.   This research investigates how high-rise apartment blocks can be better designed for the New Zealand context – specifically, how the provision of quality outdoor space can better align this typology with New Zealanders’ affinity with the outdoors.   Three innovative high-rise typologies are tested on a central Wellington site. Each is designed for a different user group and provides occupants with private outdoor space that facilitates outdoor activities usually inhibited by high-rise apartment living. Accessways are investigated and reimagined as vibrant common spaces that provide occupants with additional outdoor space.   The design outcome provides residents with a diverse range of outdoor space. From common, semi-private, and fully private, this research demonstrates a range of outdoor spaces can exist in a high-rise setting. The design outcome shifts the high-rise apartment from an imported international model to a typology adapted to the New Zealand locale.</p>

In the 1930s New Zealand was yet to invest in inner-city living via large scale apartment buildings. Few examples of flats existed. A. Sinclair O'Connor's Courtville (1914-19) at the corner Waterloo Quadrant and Parliament Street, Auckland, and Francis Petre's Manor Place Flats in Dunedin were exceptions to conventional living. In the 1930s greater interest was shown in the design of inner-city apartments – most famously by the Department of Housing Construction's Berhampore Flats, Adelaide Rd (Wellington, Gordon Wilson, 1938-40), and Symonds Street Flats, Symonds Street (Auckland, Friedrich Neumann, 1939-47), anticipating their 1940s work: the Dixon Street Flats, Dixon Street (Wellington, 1940-44), the Maclean Flats, The Terrace (Wellington, 1943-44), the Hanson Street Flats, Newtown (1943-44), and the Greys Avenue Flats, Greys Avenue (Auckland, 1945-47). [NEW PARAGRAPH] In Wellington, Edmund Anscombe dominated the design of privately funded inner city flats, designing six art-deco/modernistic apartments during this time: Belvedere, Hamilton Flats, Olympus, Linfield, Alberts Flats and Franconia. This paper examines these apartments in the context of Anscombe's comments on house design, and housing, and his 1936 proposal to replan the area of Adelaide Road as a residential area to accommodate superblocks of high rise apartments.

The specific nature of high-rise investment projects entailing long-term construction, high risks, etc. implies a need to improve the standard algorithm of cost-benefit analysis. An improved algorithm is described in the article. For development of the improved algorithm of cost-benefit analysis for high-rise construction projects, the following methods were used: weighted average cost of capital, dynamic cost-benefit analysis of investment projects, risk mapping, scenario analysis, sensitivity analysis of critical ratios, etc. This comprehensive approach helped to adapt the original algorithm to feasibility objectives in high-rise construction. The authors put together the algorithm of cost-benefit analysis for high-rise construction projects on the basis of risk mapping and sensitivity analysis of critical ratios. The suggested project risk management algorithms greatly expand the standard algorithm of cost-benefit analysis in investment projects, namely: the “Project analysis scenario” flowchart, improving quality and reliability of forecasting reports in investment projects; the main stages of cash flow adjustment based on risk mapping for better cost-benefit project analysis provided the broad range of risks in high-rise construction; analysis of dynamic cost-benefit values considering project sensitivity to crucial variables, improving flexibility in implementation of high-rise projects.

<p>Living on the edge critiques oppressive aspects of urban living. It advocates façade occupation to enhance the experience of density and enrich the street edge to achieve a vibrant and metropolitan New Zealand.   Sited in Te Aro, Wellington Central, the project proposes a citywide inversion of the typical high-rise building layout, relocating primary circulation to the street edge to dramatically reform the spatial relationships between dwelling, building and street.   The project is an inhabitable facade system comprised of various combinations of the colannade, the gallery and the annexe. This can be applied to existing or integrated with new buildings and varied in response to specific street conditions.   By creating multifunctional outdoor living integrated with circulation spaces, the design offers a vision for vertical communities with enhanced dwelling amenity to encourage more New Zealanders to embrace high density living.</p>
