Abstract

One of the most important basic needs of the affected people after natural disasters such as floods and earthquakes is to live in a safe and suitable place. The costly and time-consuming process of establishing permanent housing will provide temporary residence. Using of the disadvantages of common materials, such as steel and concrete, due unconventional extractions, exorbitant construction and production costs, and irreparable environmental damages, the need to build temporary shelters, fast construction, recyclable, environmentally friendly, low-cost and biodegradable natural resources, like bamboo, is very much felt in our beloved country. Bamboo is used as a structural material in more than 60 countries in the world, which fortunately, its species can also be found in our country. The purpose of this study is to investigate the mechanical properties and structural efficiency of the native Iranian bamboo species with the local name Kara and also design and propose a temporary green structure resistant against lateral loads. The Chevron brace was used as a lateral bearing element and hose-clamp connections were also employed. The results of compression, tensile, shear, shear with hose-clamp, and bending test parallel to the fibers were calculated to be 66.5, 103.42, 2.63, 2.73, and 137.96 MPa, respectively. The results of the analysis and design of the constructed model also indicated that the calculated demand under all load combinations in the elements of columns, beams, and braces for bending and axial stresses was more than 97%, and for shear stresses was more than 57% lower than the allowable capacity of the regulations
