Publish Year note: First published Janurary 1st 2011
Traditionally a building material of hot climate zones in Asia and Latin America, bamboo is increasingly discovered by architects of the Northern hemisphere as well. It is lightweight, highly elastic and ductile, and in addition offers qualities especially in demand in an era of limited resources, renewability and abundant availability.
Architects and engineers have significantly widened the applications of bamboo in recent years and today even wide-span bridges can be built from it. Impressed with its technical and aesthetic possibilities, European, Japanese and North American architects have adopted bamboo for a variety of construction tasks, ranging from exclusive private residences to experimental pavilions, and from airy canopies to schools or museums.
The book provides a detailed manual for bamboo constructions and presents a broad selection of built examples, among them the spectacular bamboo pavilions of the 2010 Shanghai World Exposition, a parking garage in Leipzig, Germany, the Nomadic Museum in Mexico City and Richard Rogers Terminal 4 at Madrid Airport.
To successfully make a plank, it is necessary to use mature, recently cut bamboo that is sufficiently moist. 7.1 7.2 7.3 7.4 basic construction elements 33 7.5 7.6 Planks have been popularly used without plaster (stucco) in rural houses in tropical climates (7.5), and also with stucco in urban houses. These days in Latin America, planks are used as economical formwork for concrete structures and as stabilising elements in the construction of bamboo cane walls (see p. 110f.), and also as
connection made with a “chonta”, a pin made from a very hard palm tree, resistant to termites, the sun’s rays, moisture and microorganisms. Figure 9.24 displays the use of inclined pins as connectors between parallel canes to make a stronger beam. Figure 9.27 shows a solution by Jörg Stamm, built for the end of a double truss. This solution guarantees an optimum transfer of forces through wooden pins. If the forces transferred are great, it is advisable to fill the internodes that receive the
Constructive Elements and Systems Columns Columns are linear, vertically positioned construction elements that transmit compressive forces. It is important to keep in mind that any compressive forces transmitted by the cross-section are the same at both the top and the base of the column. A frequent solution for the base is to fill the cane with cement mortar up to the first node, to prevent the cane from opening or splitting; for more security, a metal covering can be installed, surrounding the

simplest method to dry the canes is to arrange them in a form similar to a tripod, exposing them to the sun and wind (3.1). The process of drying is optimised in a greenhouse with a plastic enclosure. It is favourable to open it at night so that the less humid air can enter, and close it during the day. Figure 3.2 shows a method practiced by Ecobamboo, Colombia, where hot air is injected into the bamboo by a fan that transfers the heat from a solar collector, pushing it through a sleeve into the
