Chinese Seniors

The aim of this paper is to narrow the gap between the theoretical findings from past studies and current open space development through evaluating the behavior pattern and landscape preferences of seniors in urban parks in China. Combining an on-site observational approach with a questionnaire, the research has taken place in two successful traditional comprehensive parks in Xi’an, Shaanxi, China. The results for time, place, and activities were analyzed and depicted in figures. Design guidelines have been provided based on the analysis; new perspectives for further investigations have been pointed out for landscape architects and urban planners to carry on exploring the process of establishing a successful age-friendly outdoor space.

Outdoor Space

PurposeThe fundamental lifestyle changes, economic concerns, property price increase and construction cost can explain the transformation of traditional housing layouts to massive indoor planes by prioritizing indoor over outdoor spaces. That is, overlooking the effect of outdoor spaces, on life quality, to compensate for indoor spaces expansion. As a result, this study highlighted outdoor spaces and their impact on psychological wellbeing, especially through the enforcement of quarantine conditions and social distance.Design/methodology/approachTo achieve that, a spatial analysis for (70) apartments, in Amman, was undertaken to understand outdoor space in terms of spatial configuration, size, adjacent spaces and usage. An assessment for outdoor space based on both users' and professionals' perspectives to discuss the current situation condition in terms of physical layout, activities, area, spaces' treatment and associated incentives. (125) responses were collected from the head of household living in an apartment through using a structured questionnaire. In addition, feedback in terms of dynamics home components, home buyers' market trends and local regulations were collected from (22) professionals.FindingsStudy results have shown that apartments' buildings in Amman are deficient, quantitatively and qualitatively, in both apartments with outdoor spaces in general and units on typical floors without outdoor space in specific. While, quantitative deficiency is associated with the poor layout in terms of area, functionality and variety. Qualitative is related to the absence of nature inspiration that incorporates five senses. As a result, this underlines the need for formulation design guidelines and strategies considering psychological wellbeing to improve outdoor spaces as a hub for activities.Originality/valueHighlight the value of introducing post-pandemic multi-family housing that could lead to changes in building codes and design strategies to enhance psychological wellbeing of residents.

Ultra-high-performance concrete (UHPC) is a special concrete mixture with outstanding mechanical and durability characteristics. It is a mixture of portland cement, supplementary cementitious materials, sand, and high-strength, high-aspect-ratio microfibers. In this paper, the authors propose flexural design guidelines for precast, prestressed concrete members made with concrete mixtures developed by precasters to meet minimum specific characteristics qualifying it to be called PCI-UHPC. Minimum specified cylinder strength is 10 ksi (69 MPa) at prestress release and 18 ksi (124 MPa) at the time the member is placed in service, typically 28 days. Minimum flexural cracking and tensile strengths of 1.5 and 2 ksi (10 and 14 MPa), respectively, according to ASTM C1609 testing specifications are required. In addition, strain-hardening and ductility requirements are specified. Tensile properties are shown to be more important for structural optimization than cylinder strength. Both building and bridge products are considered because the paper is focused on capacity rather than demand. Both service limit state and strength limit state are covered. When the contribution of fibers to capacity should be included and when they may be ignored is shown. It is further shown that the traditional equivalent rectangular stress block in compression can still be used to produce satisfactory results in prestressed concrete members. A spreadsheet workbook is offered online as a design tool. It is valid for multilayers of concrete of different strengths, rows of reinforcing bars of different grades, and prestressing strands. It produces moment-curvature diagrams and flexural capacity at ultimate strain. A fully worked-out example of a 250 ft (76.2 m) span decked I-beam of optimized shape is given.

Abstract: XT Square is a kind of building having cultural commerciality function. The existence of this building is very important in supporting artists who live within it. Layout pattern becomes one of accessibility factors in XT Square area. Configuration and visibility shape influence the use of space pattern and people’s interest pattern in accessing every space in the building. The setting system between indoor space and outdoor space will give an easy effort for the people in living in and recognizing the space that it can be accessed comfortably. Configuration and visibility approachs are used in order to analyse the accessibility level of the space usage in that area. The result of the visibility and configuration analysis shows that there are many spaces having low integration that blocks do not integrated strongly and low visibility influences the appearance of the building in that area. This research suggest to open the visibility barrier and give high visibility that it can be recognized.Keywords: configuration, accessibility, visibility, system setting Abstraksi: XT Square merupakan bangunan dengan fungsi komersial budaya. Keberadaanya menjadi sangat penting guna mendukung pengrajin kesenian dan budaya di Kota Yogyakarta. Pola layout menjadi salah satu faktor aksesibilitas dalam kawasan XT Square. Bentuk konfigurasi dan visibilitas mempengaruhi pola pengunaan ruang dan pola keterarikan orang dalam mengakses setiap ruang dalam kawasan. Sistem setting antar ruang dalam dan ruang luar menjadikan kemudahan penguna dalam menempati ruang dan pengenalan ruang sehingga ruang menjadi nyaman untuk diakses. Pendekatan yang digunakan adalah pendekatan konfigurasi dan visibilitas, guna menganalisis tingkat aksesibilitas pengunaan ruang dalam kawasan. Hasil analisis visibilitas dan konfigurasi menunjukkan bahwa terdapat banyak ruang dengan integrasi lemah sehingga blok tidak saling terintegrasi dengan kuat serta rendahnya visibilitas setiap bangunan dalam kawasan. Penelitian ini memberikan rekomendasi dengan membuka pengahalang visibilitas dan memberi kantung tangkapan visibilitas agar ruang mudah dikenali.Kata kunci: konfigurasi, aksesibilitas, visibilitas, sistem setting
