Week 1 ! !

Constructing Logbook! We thought there would be less risk of premature collapse of the structure if we left a gap for ‘dinosaur access’ rather than remove bricks at the end of construction.

Dead loads - “static loads acting vertically downward on a structure.”! The greater the load and weight meant a greater compression

We struggled with the need to make a form of shelter for the dinosaur. We couldn't see a stable way of forming a roof extending form the walks so we thought the bet options would be to make a structure independent of the walls that didn't jeopardise the hight of the structure.
We used a stretcher bond for the whole structure but with small gaps between the MDF bricks to be time and material efficient
! ! ! ! ! !
Before continuing to build up the height, we changes the form to have rounded corners, thinking that this would eliminate weak points which we considered to be the corners of the rectangular form

Part of the structure became out of line, threatening to collapse outward as we got higher.
Week 1 !
Team A - final structure !
!
Constructing Logbook!
This group supported the arched gap with concrete bricks until the smaller bricks built above were able to support themselves and the load could be transferred to the the other wooden bricks that made contact with the table.!
!
Deconstruction - the structures that were enclosed at the peak tended to cave in on themselves then the weight at the peak became too much. Team B (Us) - final structure !
!
Our structure differed from the other groups because we were the only group that didn’t try to enclose the structure so we continued to build a simple form vertically rather that decreasing the diameter until the bricks came together. !
!
Deconstruction - because out external structure was open the whole way up it did not collapse in on itself but when we built one side up higher than the rest it became unstable and fell outwards.

Key Terms !
!
Load path - The route a force takes through a structure, from the point of application to the point of exit.1!
!
Masonry - Block of natural stone, artificial stone products, bricks and similar materials, usually in its constructed form with mortar or render.2!
!
Compression - to apply pressure by imposing loading whereby the effects of the pressure cause a squeezing together (of materials or material particles).3!
!
Reaction forces - an equal but opposite force acting on a body.4!
!
Point load - a point where a bearing/structural weight is concentrated and transferred to the foundation.5 !
!
Beam - rigid structural members designed to carry and transfer transverse loads across space to supporting elements.6
