“…The results obtained in the present research are similar even though the present study is made of concrete and masonry. In contrast, in the work done by (Olaya et al, 2014) and (Bianchini et al, 2016) there is an increase in floor drift. It is not feasible to make a numerical comparison since the structures are different; while in the first reference a one-story prefabricated structure was the scope of study, in the second one a reinforced concrete story structure was the scope of research.…”

“…The roof of this house got four uniaxial seismic accelerometers and through computational modeling, the researchers reported an increase of 241% in the tensile stresses associated with the load combinations and a 56% increase in natural structural period (Olaya et al, 2014). A study using numerical methods characterized a reinforced concrete moment resistance frame, with a 3, 6 and 8 story configurations.…”

In recent years, ideas such as green roofs gained importance as an alternative for environmental adaptation of society to new ambient conditions. In Bogotá city, the roofs at popular neighborhood represent a potential area for their implementation. This present research discusses how the weight of a green roof impacts a selfconstruction dwelling unit from a structural capacity demand point of view. Green roof weight is a random variable whose normality was investigated through the Shapiro-Wilk goodness of fit. The magnification factors for this dead-like load come from the Nowak-Collins method using the confidence intervals on the mean weight value. The ATC-40 pushover methodology helped in finding the non-linear behavior of a controlled but similar structure as those found in the popular neighborhoods of Bogotá city. According to this methodology, damage caused on these structures due to seismic demand increases by the green roof incorporation. However, damage increase is a function of local soil conditions.

“…17 In addition, the families (the owners) can take part in the construction process, creating a sense of attachment to the project’s success. This type of eco-productive green roof has been studied from different points of view – productivity 18 and seismic evaluation 19 – but the hydrological benefits have not yet been thoroughly studied.…”

In peri-urban areas of Bogota, people harvest and use untreated rainwater. Initial research indicates that water collected from roofs contains high turbidity values, as well as high concentrations of total suspended solids, biochemical oxygen demand 5-Day and heavy metals. Moreover, these areas do not generally have access to public sewer systems. An eco-productive green roof with the aim of reducing poverty and improving the quality of life of the communities located peri-urban areas of Bogota has been described and examined. These eco-roofs are made with cheaply attainable materials (e.g. recycled plastic bottles). The aim of this study was to understand the hydrological benefits of this type of green roof. We built an experimental setup consisted of six independent eco-roof modules planted with different crop plant species and a reference roof to serve as a control. The results obtained showed that the crop type had significant influence over the results of both hydrological behaviour and pollutant concentrations measured on the runoff from roofs. The eco-roof can retain up to 65% of the runoff volume and can reduce the runoff peak up to 80%; the eco-roof helped in retaining high concentrations of zinc. The results obtained represent a meaningful positive impact for the eco-roofs tested for stormwater harvesting and suggest that these systems could offer hydrological benefits that might help re-establish hydrological values for marginal urban areas.
