Based on the theory of space syntax, this research conducts a quantitative study on the four stages of Zhanjiang urban spatial organization system, and draws the urban evolution process. This study found that the development strategy of different periods has a huge impact on the urban development. It determines the structural basis of the original urban space and creates strong development inertia. According to these research results, it can provide an effective theoretical reference for the future spatial expansion of the city.
With the rapid development of China’s urbanization, a large number of people have moved from rural to urban areas. People have proposed higher and more urgent needs for the urban environment. Particularly, the urban street landscape is close to people’s lives, and the upgrading of design methods can improve the quality of life. Besides, the application of artificial intelligence design has become possible as information technology develops. In this paper, a visual simulator is established through algorithm models and applied to street landscape design.
The aim is to derive an expression to calculate the natural frequencies and plot the mode shapes of a simply-supported beam with an overhang with an end overhang point mass by using the Euler-Bernoulli theory in the case of free transverse vibrations. The results are validated by finite element analysis. The importance of the system presented is that it can represent machine tool spindles or even machining tools like boring bars. The results are in good agreement with the results from the finite element analyses. The derived expression can be used in optimizing the value of the point mass and optimizing the support location for better performance of the system without the need to perform complex analysis to obtain the values of the natural frequencies and to plot the mode shapes.
Flexibility represents one of the main elements of the sustainable architecture. Flexibility is important, especially for the multi-family apartments the useable surface of which is rather small. For the families with low incomes and social cases, flexibility represents a very important element given that can change the function based on the change of family structure. The aim of the research was post occupancy evaluation of subsidized housing, where it was realized that they do not meet the needs of residents, therefore were proposed changes in floor plan based on the average number of family members, realised through annexes. During this research work, analytical method, administration of questionnaires and observation period method was used.
In this research work existing laboratory tests of slim floor beams with solid monolithic concrete slab were modeled and analyzed using GID and Atena software. After validating the advanced finite element model with the test results of the international literature, structural parameters were analyzed with the aim to study their influence on the load bearing and deformation capacity of the beams. The parameters were related to the geometric of the beam: size of web openings and top concrete cover. With these results conclusion can be noticed that focusing on the optimal arrangement of the geometrical parameters of the composite beam could lead to better structural behavior with more economical solutions.
The optimization of high-rise office buildings' envelope and the application of energy-efficient measures have become a priority nowadays. Therefore, this investigation aims to assess the role of the façade's geometry design factors, e.g., folded façade perforation, window orientation, and window-to-wall ratio on building comfort and energy performance. The energy simulations were performed using IDA ICE 4.8 thermal simulation program to evaluate the thermal and visual comfort and the energy consumption of various façade test models. The optimization resulted in a façade model with a great level of thermal and visual comfort as well as a total energy reduction of 14%, representing a good compromise solution in the trade-off between thermal and visual comfort as well as energy efficiency.
Nowadays, it is increasingly important to develop economical construction processes and determine predictable costs. The current level of technology offers countless, even undeveloped opportunities to support architectural, engineering, and construction processes. Building information models created as results of design processes and databases associated with them can provide an appropriate base to fulfill the requirements. However, this information is mainly available only for the largest projects; the possibilities offered by traditional editable vector files (e.g., *.DWG) should also be examined. This study analyzes the efficiency increasing possibilities that can be achieved using low-detail 3D models generated by algorithms and applying 2D-based digital quantity estimation workflows.
Frame structures are defined as structures built of straight, less often curved bars, which are dimensioned to carry a planar or spatial load. These frames are generally considered statically indeterminate structures so that several methods can be used to determine their loads, but all of them require some simplification. This paper is not concerned with investigating these theories for determining the stresses but with the optimum design of a frame structure for a given geometry. Several different loads have been considered, where the value of the wind load in the horizontal direction has been considered. The optimization problem is mathematically formulated so that both compressive forces and bending moments acting on the horizontal beam and the vertical column, and their composite loads, are below the limit set by the material properties. The column connections were assumed to be fully rigid, and welded I-section were considered for both columns. For local bending conditions, the Eurocode 3 specification was applied. Several steel grades were tested during the investigations, and fire loading was considered an additional load. In this case, a higher safety factor was assumed to make the times to collapse comparable.
Vernacular architecture is the source of the historical development of architecture and the carrier of traditional culture. It is also the emotional sustenance of contemporary Chinese people’s beautiful homesickness. With the rapid expansion of urbanization in China, a widespread phenomenon of “hollow villages” has emerged in rural areas, and there are many abandoned rural buildings all over the countryside. Therefore, the protection and sustainable development of rural architecture are imminent. Based on the author’s rural construction project in China, this research integrates environmental psychology and architecture and tries to build a high-quality living environment, aiming to explore a new design strategy to meet the challenges in the future.
The historic zone of Prishtina is part of the city that represents the historic and environmental values of the city, with a rich built heritage as residential, commercial, handicraft, religious. Unfortunately, this rich heritage is heading towards total loss from the neglect and various degradations that are taking place. This research aims to analyze the urban structure of the historic zone of Prishtina, in particular Vasil Andoni Street. Based on the results from research methodology used, comprised from analysis, comparisons, interviews, and questionnaire, this paper aims to give a design proposal for urban revitalization of the Vasil Andoni Street, that would provide the sustainable development of the area, in physical, social, economic and spatial aspect, while protecting and respecting the cultural heritage of the zone.
