桩—土—上部结构振动台试验相似问题研究

桩—土—上部结构相互作用的研究已成为抗震工程中的重要课题,但因其相互作用的复杂性,这方面的研究并不成熟,尚需进行深入地探讨和研究。在桩—土共同作用下,就地基对上部结构的影响以及上部结构对地基的影响,这两种不同情况的相似问题进行了研究,给出了振动台模型试验设计的一般步骤。由相似理论得出了桩—土—上部结构在通常情况下的相似关系,并给出了实例分析。研究表明:试验目的不同,考虑的主要影响因素不同,主要相似关系亦不同。

e-BIM: a BIM-centric design and analysis software for Building Integrated Photovoltaics

Building Integrated Photovoltaics (BIPV) has gained large popularity in recent years. However, its effective design remains challenging. Different but often related design concerns regarding BIPV are normally treated, in the current practice, in multiple but separated design phases with different models and tools. The complexities in maintaining the consistency between those models employed in separated phases make seamless PV and building integration, one of the major concerns of BIPV design, far from satisfying. To this end, this paper proposes a uniform BIPV design platform: e-BIM, which is a BIM (Building Information Modelling) - centric BIPV design and analysis software platform, to address the related design concerns via one uniform data model. The concept of domain-specific models is introduced to allow the external PV-related models to be integrated into the uniform model. To simplify model synchronization problem, the domain-specific views corresponding to specific domains are provided to designers and meanwhile a synchronization engine is developed to automate data consistency among views and the uniform model. The current prototype is developed based on Autodesk® Revit and tested in a practical BIPV application. The results show that this platform achieves seamless BIPV design for architects, PV system designers and electricity professionals. Moreover, compared to the initial BIPV design, the photovoltaic system cost is reduced by 11.7% and the transmission losses by 2.95%.

Building-integrated photovoltaics (BIPV) in architectural design in China

Building-Integrated Photovoltaics (BIPV) are one of the best ways to harness solar power, which is the most abundant, inexhaustible and clean of all the available energy resources. This paper discusses issues concerning BIPV in architectural design in China, including how to choose between BIPV and building-attached photovoltaics (BAPV), whether it is necessary for photovoltaic components to last as long as buildings and how to design BIPV structures. The paper shows that we should consider the function, cost, technology and aesthetics of BIPV, rather than solely the high integrations. According to developments in technology and markets, photovoltaic structures and design should be focused on the maintenance and replacement of photovoltaic cell modules, rather than simply prolonging their lives. To solve problems associated with the existing photovoltaic structures in China, we design a building photovoltaic structure that allows convenient maintenance and replacement of photovoltaic components.

Compromises between form and function in grid-connected,building-integrated photovoltaics (BIPV) at low-latitude sites

The integration of photovoltaic (PV) modules on building façades and rooftops is an ideal application of solar electricity generators in the urban environment. Maximum annual performance of grid-connected PV is usually obtained with modules tilted at an angle equal to the site latitude, facing the equator. The performance of PV systems not tilted and oriented ideally can drop considerably, depending on site latitude. With grid parity – when the cost of solar electricity becomes competitive with conventional electricity – expected in many countries in the present decade, a more widespread application of PV on buildings is expected, and in this context the main goal of this paper is to demonstrate that good compromises between form and function are possible. In this work we compare the annual energy generation of a curved BIPV system installed as a car port rooftop, with an ideally-oriented and tilted, flat BIPV system installed as a building’s rooftop cover at a low-latitude site (27°S). For the one-year period analysed, the curved-shape BIPV system annual yield was 12% lower than that of the reference BIPV system, and during the summer months (November to February), the curved BIPV installation presented a higher energy yield than the latitude-tilted generator. With these results we show that a good compromise can be reached between form and function in BIPV systems.
