Ultimate Capacity of Timber Joints.

Aim: To determine the ultimate capacity of nailed and bolted connections and the modes at which they fail. The observational results give be compared to the estimates predicted using AS 1720 - 1998. Equipment: Timber extremity (with nails or bolts connection) Scale Ruler debauching frame 3 dial gauge Electronic readout Load cell regularity: See Lab notes Measurements See next page 10 Tone actuator A = 1450 mm2 Span = 2 m Results Nails Load (psi)         Load (kN)          deviation 1 (mm)         Diff Defl 1 (mm)         Deflection 2 (mm)         Diff Defl 2 (mm)         Deflection 3 (mm)         Diff Defl 3 (mm)         Average (1 & deoxyadenosine monophosphate; 3) (mm)         Moment (kNm)         D (mm)         R (mm)         Curvature (mm) 0         0.00         48.86         0.00         96.56         0.00         47.50         0.00         0         0.00         0.00         0.00         0.00 200         2.00         48.39         0.47         96.11         0.45         46.94         0.56         0.515         0.50         0.06         1923076.96         5.2E-07 400         4.00         47.48         1.38         94.61         1.95         45.93         1.57         1.475         1.00         0.48         263158.13         3.8E-06 600         6.00         46.64         2. 22         93.22     Â!  Â Â Â 3..34         44.98         2.52         2.37         1.50         0.97         128866.46         7.75997E-06 800         8.00         45.82         3.04         91.94         4.62         44.16         3.34         3.19         2.00         1.43         87413.30         1.14399E-05 1000         10.00         45.01         3.85         90.69         5.87         43.39         4.11         3.98         2.50         1.89         66138.51         1.51198E-05 1200         12.00         44.16         4.70         89.37          7.19         42.61         4.89         4.795         3.00         2.40         52193.26         1.91596E-05 1400         14.00         43.29         5.57         87.99         8.57         41.83         5.67         5.62         3.50         2.95         42374.36         2.35992E-05 1600         16.00         42.23         6.63         86.20         10.36         40.82         6.68         6.655         4.00         3.71         33740.04         2.96384E-05 1800         18.00         40.97         7.89         84.04          12.52         39.66     !     7.84         7.865         4.50         4.65         26855.17         3.72368E-05 2000         20.00         39.18         9.68         80.85         15.71         38.01         9.49         9.585         5.00         6.13         20411.23         4.89926E-05 2200         22.00         37.49         11.37         77.90         18.66         36.42         11.08         11.225         5.50         7.44         16816.09         5.94669E-05 2400         23.99         34.98         13.88         74.50         22.06         33.87         13.63         13.755         6.00         8.31         15055.33         6.64217E-05 2600         25.99         32.98         15.88         72.29         24.27         31.90         15.60         15.74         6.50         8.53         14658.43         6.82201E-05 2800         27.99         31.02         17.84         70.42         26.14         30.01         17.49 ...
