Code compliance of fully glazed tall office buildings in hot climate

In this research, the effect of glazing type and other energy conservation measures on the peak power demand of air-conditioning (AC) systems is investigated for tall and fully glazed government and private office buildings. The EnergyPlus building simulation program is used in the analysis assuming climate conditions similar to that experienced in hot countries of the Arabian Gulf, such as Kuwait. The main objective of the investigation is to meet the limits stipulated in the mandatory Kuwaiti code of practice for energy conservation, with respect to peak AC demand, for both air-cooled and water-cooled AC systems. It is found that for government office buildings with air-cooled AC system, the code limit of 70 W/m² for the AC peak power is met when tint low-e glazing is used with either heat recovery units or with AC systems with higher coefficient of performance (COP); whereas for private office buildings, the limit can be met when using a number of conservation measures. Overall, the water-cooled AC system showed better performance even though the code limit is 50 W/m² which is mainly due to the higher COP values achievable with such AC systems.

Detection of damage locations and damage steps in pile foundations using acoustic emissions with deep learning technology

The aim of this study is to propose a new detection method for determining the damage locations in pile foundations based on deep learning using acoustic emission data. First, the damage location is simulated using a back propagation neural network deep learning model with an acoustic emission data set acquired from pile hit experiments. In particular, the damage location is identified using two parameters: the pile location (P_L) and the distance from the pile cap (D_S). This study investigates the influences of various acoustic emission parameters, numbers of sensors, sensor installation locations, and the time difference on the prediction accuracy of P_L and D_S. In addition, correlations between the damage location and acoustic emission parameters are investigated. Second, the damage step condition is determined using a classification model with an acoustic emission data set acquired from uniaxial compressive strength experiments. Finally, a new damage detection and evaluation method for pile foundations is proposed. This new method is capable of continuously detecting and evaluating the damage of pile foundations in service.

Potential of emerging glazing technologies for highly glazed buildings in hot arid climates

In order to improve the sustainability of buildings one of the challenges is to address the role of the building envelope as the key climate moderator between the internal and external environments. The envelope is exposed to the elements and needs to control air exchange as well as sunlight and sound passing through to the occupants. Therefore, it has a major impact not only on the energy utilisation within the space it controls but also on the quality of comfort. However, inside highly glazed modern buildings, achieving good comfort is often at the cost of high-energy consumption. Therefore, in the light of ever increasing energy costs, improved façade design can contribute to a reduction of operational costs. The aim of this paper is to explore technical, economic, environmental and indoor comfort implications of emerging glazing technologies for energy control of highly glazed buildings in arid Middle Eastern climates, which is one of the harshest climates for this building type. The work includes predictions through thermal simulation of the impact of electrochromic glazing, holographic optical elements (HOE), aerogel glazing and thin film photovoltaics on two example buildings. Potential reductions in cooling demand are assessed.

Drift control and damage in tall buildings

The interstorey drift limitations in earthquake codes of various countries around the world, have been reviewed. It is emphasized that, the aseismic safety of a tall building as well as its susceptibility to nonstructural damage are primarily indexed to its ability to restrict the relative storey displacements, in addition to its adequate strength, ductility and toughness. A moment resisting frame building satisfying all requirements of strength and ductility may still be subject to severe nonstructural damage, if the interstorey drifts are not restricted properly by means of shear walls. Several stringent deflection criteria as well as a damage control index are introduced to be conscientiously determined and checked during the design calculations for the purpose of controlling damage especially to nonstructural elements.     

地铁隧道下穿历史风貌建筑影响的实测与分析

两座历史风貌建筑物紧邻地铁车站,并且盾构在其下方穿越,需对建筑物的变形进行严格控制。对建筑物的保护,针对性提出地面袖阀管注浆加固、车站基坑盖挖逆作法、地连墙截断承压水、冻结、车站内水平注浆加固、优化盾构机掘进参数等施工方案及措施。通过对基坑开挖与降水、端头加固、盾构掘进等阶段的监测数据进行分析,研究了不同施工阶段对建筑物变形影响的规律及特点,实测结果表明：合理的盾构掘进参数能够将建筑物的沉降控制在较小范围内;冻结孔施工、地下水通过冻结区盾尾间隙进入刀盘前方等均可引起建筑物的显著沉降;建筑物基础与隧道之间存在淤泥质土层时,在淤泥质土层下方进行注浆不能对自重较大的建筑物进行有效抬升,但对自重较小建筑物的抬升则有一定的效果,但注浆在淤泥质土层中引起孔压的消散可导致建筑物在后期产生沉降;盾构机进入冻结体前应做好全断面注浆止水,切断前后水力联系,盾构机掘进困难时,不应随意增大盾构推力。     

Deposition of particles on gypsum-rich coatings of historic buildings in urban and rural environments

Deposition of gaseous and particulate atmospheric pollutants causes decay of historic mortars to give gypsum-rich coatings by sulphation of lime mortars and blackening of gypsum mortar, resulting in gypsum coatings. Particulate pollution emitted by industrial sources and vehicular traffic is responsible for the deterioration. XRF and SEM analyses of these coatings and their comparison with both the composition of dust coatings formed by the deposition of gaseous and particulate matter in an urban and a rural locality allows assessing which pollution sources are the most damaging for these materials, knowing the elemental composition of these emissions.     

深基坑开挖导致邻近建筑群大变形损坏的实测分析

深基坑开挖对邻近建筑物的变形和安全有着重要的影响,然而,深基坑自身安全开挖却导致邻近建筑群变形损坏的工程实录却并不多见。为此,结合某高档综合楼12 m深基坑开挖工程施工过程的现场监测结果,分析了深基坑开挖导致邻近11幢建筑物的沉降变形发展过程,及其与地基条件、基坑开挖施工工序、支护结构水平位移、建筑物基础型式之间的关系。结果表明,深厚的淤泥质粉质黏土夹粉砂地基及基坑降水是诱发6幢建筑物产生超过100 mm沉降变形而损坏的根本原因,有效的止水帷幕和降水措施是控制该类地基深基坑开挖工程对邻近建筑物影响的关键。
