Week 4 First of all, we placed two pieces of timber on the vertical, since they can be more stable in such position. Then, use nails to combine the thin board with the two pieces of timber mentioned above. The last step can be a bit complex. Firstly, measure the width of the combination. Secondly, use the data to make converted timber by saw cutting the third piece of timber. Finally, measure the length of the combination and divide it into five parts on average, pinning the converted timber on the combination. The following part is a kind of tension and compression test. The strength of material depends on its ability to sustain a load without excessive deformation or failure. Since we all use the same material, the strength of span depends on its structure. The interesting is normally the first place to collapse should be the point of junction between different types of wood, since the nail slightly damage its internal structure.
The spanning capability of horizontal elements determines the spacing of their vertical supports. This fundamental relationship between the span and spacing of structural elements influences the dimensions and scale of the spaces defined by the structural system of a building. The dimensions and proportions of structural bays, in turn, should be related to the programmatic requirements of the spaces.
