## 1 Introduction  
In Latin American countries, it is common to find social housing in rural areas since these are built for the population with lower resources [1], which are made with conventional materials such as concrete, hollow blocks, clay blocks beams and vault slabs [1]. However, the construction sector of Latin America has seen that the use of imported materials has a negative impact on the cost of the houses, something that could be changed with the utilization of native and alternative materials [2]. Nevertheless, prices are not the only problematic that social housing has to face, also, since the Oceanic Nazca plate subducts eastward beneath South America from Chile to Panama, the houses of the regions have to resist some of the strongest earthquakes in the world. For example, in 2016, the Ecuadorian shores suffered a 7.8 earthquake in the Richter Scale, making it the worst in the last years [3], where buildings suffered several infrastructure damages. In this sense, the telluric forces are an important parameter to consider for an alternative material that can be useful in social housing. In this way, taking as reference urban areas, traditionally the support of slabs and roofs are widely done with steel decking since the suppliers have promoted technical-constructive-economic advantages and it showed small damages and good energy dissipation [4]. Furthermore, taking it as a reference, there has been a growth in the implementation of steel framing construction systems as construction alternatives since it is seismic resistant, fast and effective [5]. In this sense, the application of a large steel section for structures such as moment-resist frames has the ability to dissipate cycling loads, prevents drifts and improves structural stiffness, however, this profile increases the structure weight considerably [6] and the price is not always affordable, which is why it is considered as the structure to imitate by alternative materials that can be used for low cost social housing in rural areas. The utilization of alternative materials in buildings has been researched since massive construction has led to the destruction of natural stone deposits [7], where reinforcements have been used to improve structures by increasing deformation capacity and/or its resistance [8]. Additionally, due to the need of fixing damaged structures, fiber reinforced polymers have been used in the rehabilitation of reinforced concrete structures [9]. Furthermore, the natural fibers have good mechanical properties to use as structural reinforcement in buildings [10] since fiber reinforcements enhances the strength of the base material [11], has a superior energy absorption proficiency [12] and in the design the structural engineers use materials that are determinate by market forces [13]. In this sense, fibers like coconut, SSI, jute, ramie bast, kenaf bast, abaca leaf, palm, hemp, flax, [14], cement reinforced by natural materials such as wood in particles [15], etc., are good options to be considered along with many others. In a similar way, after the Lombok earthquake of 2018, the houses that were heavily damaged reached approximately 149.706, creating the need for temporary shelter that could last, especially for people in rural areas, where timber was used, but the high demand required evaluating the implementation of other materials, where bamboo was considered for its low weight strength ratio, ductility, low cost, convenience [16] and the known fact that has a construction use [17; 18; 19]. For these cases, where there are several options, in the context of design structural elements with alternative materials is important to consider the different methodologies to make the best selection. In this sense, the designers have been helped by systematic quantitative methods who have the objective of optimizing the metrics for the best performance, looking for the maximization or minimization of an aspect [20].
