 CONSTRUCTION  LOG  BOOK  

 Tutorial  week  1-­‐  Stewart  Brooks      Loads  are  represented  as  arrows.  A  load  will  take  the  most  direct  route  to  the  ground.    Landscape  is  the  fundamental  background  to  the  constructed  city.      A  sense  is  the  direction  of  a  force-­‐  direction  and  sense  work  together.      Compression  is  a  characteristic  of  mass  consumption.    Forces  are  defined  by  direction  and  magnitude.      We  use  scales  to  represent  larger  elements  in  a  smaller  format,  smaller  elements  in  a  larger  format  and  for  practical  reasons.    E-­‐tutorials    Loads:  Dead  loads-­‐  the  permanent  loads  of  the  structure    Live  loads-­‐  something  that  can  be  applied  

                                                   

Not  sure  what  kind  of  accompanying  pictures  to  put  here????    Key  terms    Load  path:  A  path  that  seismic  forces  pass  through  to  the  foundation  of  the  structure  and,  ultimately,  to  the  soil.  Masonry:  Stone  or  brickwork,  the  work  done  by  a  mason.  Compression:  The  act  or  process  of  compressing  or  the  state  of  being  compressed.  Reaction  Force:  Newton’s  Law  states  that  for  every  force  acting  on  a  body,  the  body  exerts  a  force  having  equal  magnitude  and  the  opposite  direction  along  the  same  line  of  action  as  the  original  force.  Point  Load:  A  load  concentrated  over  a  very  small  or  tiny  area.  Beam:  A  horizontal  member  spanning  and  opening  or  carrying  a  load.

 TOWER  MAKING  

To  begin  our  tower  we  decided  to  make  a  substantial  sized  base  to  ensure  it  would  be  built  on  solid  foundations.  We  chose  a  width  of  three  blocks  which  seemed  appropriate  at  the  time  to  allow  us  to  taper  the  tower  inwards,  however  in  retrospect  such  a  bulky  and  wide  base  in  general  was  probably  not  necessary,  as  it  used  up  most  of  our  resources  on  the  lower  levels!      We  used  a  stretcher  bond  style  to  stack  the  blocks  as  we  believed  this  would  be  the  best  way  to  ensure  that  the  load  would  transfer  down  to  the  towers  foundations  even  when  the  structure  began  tapering  inward  as  it  got  higher.          After  the  fifth  story  we  decided  to  reduce  the  width  to  only  two  blocks  across.  This  was  in  an  effort  to  save  time  in  the  building  process  as  well  as  reducing  the  amount  of  blocks  we  were  using.  This  proved  to  be  a  little  more  effective  and  we  began  to  catch  up  with  some  of  the  other  towers  in  our  room,  whose  groups  seemed  to  have  decided  to  build  theirs  much  taller  and  slimmer  in  stature.

In  order  to  address  the  problem  of  ensuring  that  the  object  specified  by  the  tutor  (in  our  case  a  green  dinosaur)  could  fit  through  an  opening  in  our  structure  and  back  out  again  we  measured  the  dinosaur  in  terms  of  the  blocks  we  were  using  and  then  one  member  of  our  group  built  that  side  of  the  structure  to  ensure  that  the  dinosaur  could  fit  easily.      This  was  a  major  concern  for  us  as  we  were  worried  about  whether  or  not  the  structure  would  still  be  able  to  self  support  with  a  chunk  of  it  missing  for  the  doorway.      After  ensuring  that  the  dinosaur  was  able  to  enter,  therefore  enabling  us  to  meet  the  requirements,  we  were  running  out  of  time  and  once  all  our  blocks  had  been  used  we  began  to  experiment  with  how  much  of  our  structure  we  could  take  apart  before  in  began  to  crumble.      We  were  for  the  most  part  really  surprised  at  how  self  supporting  we  had  built  our  structure  to  be,  which  made  us  realize  we  could  have  maybe  used  a  third  or  even  half  the  amount  of  blocks  on  many  parts.    If  we  built  this  same  structure  again  we  decided  a  few  messages  would  be:  -­‐using  less  blocks  on  the  foundations  of  the  building  as  we  still  needed  it  to  reach  a  certain  height  -­‐spend  less  time  on  the  design  process  and  more  time  building.

 Demonstration  of  force/compression  forces      By  putting  four  straws  together  as  legs  the  structure  is  able  to  withstand  more  pressure  and  leads  to  more  stability.    The  structure  is  also  able  to  withstand  more  when  the  legs  are  completely  straight.    With  shorter  legs  in  theory  the  structure  should  be  able  to  withstand  a  little  bit  more  however  the  legs  proved  to  be  a  little  bit  less  stable.      Angular  structures  seemed  to  be  the  most  stable  out  of  the  different  types  that  were  constructed.        Week  2  e-­‐learning:

TOWER  BUILDING  WEEK  2  This  week  we  had  to  use  balsa  wood  and  glue  to  create  the  highest  structure  we  could.  A  member  of  our  group  kindly  cut  up  the  wood  so  that  we  were  able  to  start  constructing  as  soon  as  the  time  started.  He  had  sliced  the  wood  very  thinly  which  allowed  us  to  have  40  pieces  however  some  of  them  were  not  very  stable  whatsoever.    As  a  group  the  planning  process  took  us  longer  than  for  the  previous  week  due  to  the  fact  that  we  were  determined  to  learn  from  last  week  and  concentrate  on  building  height  instead  of  worrying  too  much  ensuring  our  structure  was  super  stable.    We  discussed  a  few  possible  shapes  for  our  structure  to  take  before  deciding  on  a  triangle  base  with  triangular  reinforcements  on  each  level  to  ensure  the  structure  could  support  itself.      This  proved  to  be  effective  and  as  each  member  of  the  group  found  a  job  for  ourselves  we  began  building  quite  quickly.    We  decided  on  two  triangles  of  60x60x60cm  for  the  base  and  first  level,  followed  by  40x40x40cm  for  two  levels  then  finally  20x20x20.
