To improve the mechanical performances of joints in prefabricated construction, a type of connection structure with long-fiber and metal laminated bolts (referred to as a fiber-metal connector) is proposed and investigated by simulation and theoretical methods. The results include the following: (1) The fiber layer in bolts can form a second stiffness during rotation. This mechanical characteristic improves the bearing capacities and energy dissipation ability of the connector relative to the conventional metal connector, which are expected to effectively limit the elastoplastic rotational displacement of a structure. (2) For the reason, the fiber layer can bear load in the plastic phase due to its high-strength characteristic in the length direction. (3) A bilinear model for the bearing curve of the fiber-metal connector is proposed, and equations for optimization of fiber layer thickness are obtained with a target on bearing capacity and energy dissipation ability which are approximately higher 30% and 13% than that of the conventional metal connector, respectively. This research is expected to provide a theoretical basis for the application of this fiber-metal connector in engineering and improve the safety of prefabricated structures.

The external environment directly influences human health. However, what happens inside? This work deals with the effect that the interior thermal variables have on the propagation of respiratory diseases and focused on the relation of the temperature and relative humidity inside social housing in the 1040 parishes of Ecuador and the transmission of influenza. On the one hand, historical weather-related variables were used to simulate and estimate the interior conditions, and thresholds on temperature and humidity were determined. On the other hand, the health-related variable was determined by analyzing the statistics corresponding to the influenza and viral pneumonia in 2009 since that year was critical for these diseases; the data were divided by month for each parish. Finally, the correlation of these variables determines the relative importance of the interior conditions on the respiratory health of its inhabitants. The preliminary results indicate that the places with the lowest temperatures and relative humidity could favor the virus transmission. Also, the analysis indicated that respiratory diseases increase in August and October. In this way, it is clear that social housing projects in Ecuador require a study which guarantees not only energy efficiency and sustainability related issues but also the well-being of their inhabitants.

“…• Energy simulation. This study uses simulation to obtain energy use data rather than referring to statistics [34,35] or conducting field monitoring [36,37]. An important advantage of simulation is that the other two types of driving factors can be controlled at fixed levels under various scenarios of occupant information and behaviors.…”

Cooling and heating consume a large amount of energy during the operation of residential buildings in the hot summer-cold winter zone. It causes serious ecological damage and negatively affects natural resources. Occupant usage behaviors of cooling and heating systems are driven by various factors, and correlations between the driving factors and corresponding environmental impacts (EIs) are not well quantified. This study focuses on two occupant-related driving factors: household size and age composition, and combines a questionnaire survey, an energy simulation, and an EIs assessment into an integrated model. A case study is conducted in Jiangsu, China, to demonstrate the model. Nearly 1800 samples are collected from a large sample questionnaire survey and then classified into nine household types according to their household sizes and age compositions. The EIs due to cooling and heating of different household types in a typical year are then assessed and compared. The assessment results show that different household types have various environmental performance. Households with larger size, elderly people, and children have higher EIs. This newly established model is applicable and builds a bridge between driving factors and the environmental performance of cooling and heating. These assessment results will help better understand the role of household type.Sustainability 2019, 11, 5724 2 of 17 equipped with split air conditioners, varied by orders of magnitude [11]. The critical role of occupant behaviors was recognized, and this aspect has attracted more attention recently [6,[12][13][14].Cooling and heating as well as the related occupant behaviors in the hot summer-cold winter climate zone in China deserve special attention. The hot summer-cold winter climate zone covers almost half of the provinces in China with dense population and fast-growing economy. The weather is sultry in summer and cold and wet in winter. Space cooling and heating in this region is a major domestic energy consumer and pollutant emitter [2], playing an important role in China's building energy conservation task [15]. According to the Chinese heating policy, no district heating is provided in this region. Individual facilities, especially air conditioners, are widely installed and utilized for heating. Thus, air conditioners in this region are often used for both cooling and heating [16], and occupant behavior plays a significant role during the usage.Turning on, turning off, and temperature setting are three typical air-conditioner usage behaviors, and they are affected by various driving factors, including climate factors (e.g., outdoor temperature and humidity) [17,18], building and system factors (e.g., building type, building age, air-conditioning system and heating system) [19][20][21], and occupant related factors (e.g., age, gender, and income) [22,23]. Among the three types of driving factors, climate factors and building and system factors are less subjective than the occupant-related ones, which are complex and significant ...
