  1. Masonry construction - Exercise cross section Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  2. ground plan upper floor Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  3. ground plan Ground floor Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  4. ground plan Basement Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  5. ground plan Basement basement- high precision bricks 6/lm d = 300 mm fk = 2,2 N/mm2 he=2,41 m hs = 2,5 m e = 19 kN/m3 qk = 5 kN/m2 Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  6. N N M d Design load eccentricity: e = M/N e c sexist e  d/3 1. 2. σexist σpermissable Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  7. Design method Boundary conditions forsimplifiedmethod ot a basement wall d ≥ 240 mm hs ≤ 2,6m qk ≤ 5,0 kN/m2 he ≤ hs Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  8. Verification of conditions • Wall thickness d = 300 > 240 mm • Max. floor height hs = 2,5 < 2,6 m • Max live load qk = 5 ≤ 5 kN/m2 • he = 2,41 ≤ hk = 2,50 m  Use of the simplified method Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  9. Proof at half height of the fill mit N1,Rd,d = upper limit of the wall normal force N1,lim,d = lower limit of the wall normal force N1,Ed= Design value of the wall normal force from the load case Nmax and Nmin d = Wall thickness fd = Design value of the masonry compressive strength e = Weights of the fill Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  10. Verification on the top of the wall N0,lim,d = lower limit of the wall normal force (s. table) N1,Ed= Design value of the wall normal force from the load case Nmax and Nmin Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  11. load collection dead weight Gk Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  12. live load Qk Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  13. Action • for cases with only one live load Qk,1 • for cases with more than one live load Qk,i Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  14. partial safety factors of actions Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  15. for unusual effects special rules Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  16. Minimum normal force at the top of the wall (only dead load without increasing by PSF) Minimum normal force in half storey height Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  17. Maximum normal force at the top of the wall Maximum normal force in half storey height Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  18. lower limits N1,lim,d for basement walls upper limit due to load bearing capacity Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur

  19. Verification E1,lim,d = 45,98 kN/m < R1,Rd,min = 50,94 kN/m d·fd/3 = 124,67 kN/m > R0,Rd,max = 85,58 kN/m OK! Prof. Dr.-Ing. Wolfram Jäger - LS Tragwerksplanung - Fakultät Architektur
