轻集料砼小型空心砌块填充墙裂缝分析及预防措施

随着国家保护土地措施的实施,粘土砖的使用得到严格控制,再加上近年来钢筋砼结构建筑物越来越多,以及对建筑保温节能的要求也越来越高,轻集料砼小型空心砌块在房地产建设相关领域得到广泛应用。作为填充墙主材的轻集料砼小型空心砌块具有容重轻、热阻值较高等特点,用作非承重墙体时较机制红砖有较大优越性,但也有其缺点:一是胀缩率比粘土砖大,随着含水量的降低,材料会产生较大的干缩变形,干缩后的材料受潮后会发生膨胀,脱水后会再发生干缩变形;二是由于其热阻值较高,在正常使用条件与钢筋砼框架结构间会出现温度变形差;三是砌块砌体作为一种脆性材料,其抗拉及抗剪切强度较差,只有传统粘土砖的50%;四是砌块原材料及生产质量不稳定。正是由于具有上述特性,轻集料砼小型空心砌块填充墙体裂缝的质量问题也显得非常突出。墙体裂缝不但有碍美观,且会导致墙体装饰面层空鼓、脱落以及外墙渗漏等质量问题。由于其问题的普遍性,已成为一种质量通病。

Thermal performance analysis of building construction with insulated walls in summer days and nights

In the present study,the insulation mechanism of building walls during the summer days and nights is investigated with a realistic approach to enhance their performance.A fiber layer,as a porous medium with air gaps,is used along the wall layers to decrease the energy loss.Meanwhile,the radiation heat flux variation during five days in a row has been considered for each side of the building,and it is tried to reach the optimum values for geometrical factors and find suitable insulation for each side of the building.A lattice Boltzmann method(LBM) based code is developed to simulate the actual chain of the heat transfer which consists of radiation,conduction,forced and natural convection combination within wall layers including fiber porous insulation.The results indicate that for the current insulation model,the effect of natural convection on the heat transfer is not negligible and the existence of the porous layer has caused a positive impact on the heat loss reduction by decreasing the circulation speed.Also,by using the optimum location and thickness for the insulation layer,it is showed that each side of the building has different rates of energy loss during a day,and for the appropriate insulation,they need to be evaluated separately.

Protection of architectural heritage: attitudes of local residents and visitors in Sirako, Greece

Architectural heritage comprises one o the most important elements of mountain settlements in Greece. It holds high cultural value, represents the tangible continuation of the past and forms the unique character and identity of each mountain region. Yet, controversy regarding funding for its preservation often arises. In this paper, we used two Contingent Valuation surveys to estimate the socia benefit deriving from protecting the traditiona architecture in the mountainous village of Sirako and through it, to examine perceptions and attitudes o local residents and visitors. Research findings revealed a strong social will in favor of the good's protection followed by high percentages of positive willingness to pay(WTP). However, WTP is significantly higher among residents. Cultura heritage value, of the good, appears to prevail, along with the environmental one. However, both residents and visitors pointed out that local heritage, if wellpreserved, will boost tourism development. Residents appeared to better recognize the true level o architectural decay, expressed higher apprehension for its protection and were willing to pay higher amount of money. Tourists, on the other side expressed high satisfaction for their visit, appreciated the beauty and serenity emerging from local built and natural environment and spent several days visiting the surrounding area. The longer they stayed and gotfamiliar with the village, the more willing they were to contribute to local heritage's protection. Percentages reflecting indifference for protecting architecture were extremely low. Yet, they were higher among tourists. Traditional architecture is considered as public good; an opinion resulting in an important percentage of visitors stating that national government should provide the necessary funding. In addition, the architecture appears to hold a high level of topicality. Those descending from Sirako or emotionally connected to it, of both social groups,turned out to be more concerned about the good and with a stronger sense of responsibility for it. Usevalue of the good holds high economic value, as well,while higher percentages of zero WTP appeared among non-users. Research findings revealed social attitudes and perceptions on what constitutes architectural heritage, in its cultural and economic frame. If taken under consideration, they may form useful drivers for local, heritage-based, sustainable development.

Subjective annoyance caused by indoor low-level and low frequency noise and control method

The influence of low_level noise has not been widely noticed. This paper discovered that low_level and low frequency noise(A_weighted equivalent level L eq <45 dB) causes higher probability of subjective annoyance. The fuzzy mathematic principle was applied to deal with the threshold level of subjective annoyance from noise in this study; there is preferable relationship between the indoor noise and noise annoyance at low frequency noise level. Study indicated at the same centered noise level, the change of annoyance probability is mainly caused by the change of the frequency spectrum characteristic of the indoor noise. Under low noise level environment, without change of the medium_low frequency noise, the slight increase of medium_high frequency noise level with the help of noise sheltering effect can significantly reduce the noise annoyance. This discovery brings a new resolution on how to improve the environmental quality of working or living places. A noise control model is given in this study according to the acoustic analysis.

Strength and Toughness of Steel Fibre Reinforced Reactive Powder Concrete Under Blast Loading

The blast resistance of structures used in buildings needs to be investigated due to the increased threat of a terrorist attack. The damage done by Composition B or Powergel to steel fibre reinforced reactive powder concrete （SFRPC） panels and ordinary reinforced concrete （RC） panels of equivalent static flexural strength is compared. A 0. 5 kg charge was detonated at a distance of 0. 1 m from the 1. 3 m × 1. 0 m × 0. 1 m （thick） panels, which were simply supported and spaning 1.3 m. Dynamic displacement measurements, high-speed video recording and visual examination of the panels for spall and breach were undertaken. The SFRPC panels withstood the bare charge blast better than the reinforced ordinary concrete panels. Neither type of panel was breached using a O. 5 kg charge, The RC panel exhibited more spalling when Composition B was used. Under successive Composition B loading conditions, the RC panel was breached. In comparison the SFRPC panel was not breached. Exposure to fragmenting charge loading conditions confirmed these performance differences between the SFRPC panel and the reinforced ordinary concrete panel.
