1 CONSTRUCTING ENVIRONMENT LOGBOOK
WEEK 6 SPENNING AND ENCLOSING SPACE Workshop This week I took the workshop class. In this class, we are divided into group of 3 students and are asked to design and construct a structure that must span 1100 mm and the height is less than 400 mm. In our group, the material is timber
whose
size
is
1200*35*35 and 1200* 80. The left picture is our designing because this structure can carry a greater portion of the load. We make the timber plate as the top and bottom. The trusses used the timber whose size is 1200*35*35. And the angle is 45 degree because we didn’t know how to find the 60 degree. However, we ignore the character of material. The biggest problem is that the timber plate is not good as compression and you can break it by hand. Therefore, this part between two trusses is easily to break.

and a triangulated web system because it can reduce the dead loads. Cross bracing is usually seen with two diagonal supports placed in an X shaped manner, which can be preventing the frame from tilting and falling.
Glossary Rafter: is one of a series of sloped structural members (beams) that extend from the ridge or hip to the wall plate. Eaves: the bottom edge of a roof. Purlin: a purlin is any longitudinal, horizontal, structural member in a roof. Alloys: combinations of two or more metals Cantilever: a beam anchored at only one end. Soffit: the underside of any construction element. Portal frame: consist of braced rigid frames (two columns and one beam) with purlins for the roof and girts for the walls. Top chord: the top beams in a truss are called top chords
