NILAI DISAIN LATERAL SAMBUNGAN GESER GANDA BATANG KAYU TROPIS DENGAN PAKU BERPELAT SISI BAJA
ABSTRACT: Connection is the
weakest point of the structural building system. Structural construction
building system must ensure that there is only a tensile force or just axial
compression that is working on the connection. Data on the lateral design
values (Z) double shear connection wood beam with nails of steel side plates
for various types of tropical Indonesian wood have not studied much. Average
moisture content (MC) for the main member varies from 13.3 to 22.5% while
average specific gravity (r) from 0.27 to 0.76 and then wood density from 0.31
to 0.89 g/cm3. From this average value of MC, SG and wood density the lowest is
sengon and the highest is rasamala wood. Average allowable load of compression
parallel to grain ( ) and parallel tensile ( )is sengon, but the highest is bangkirai.
There is a general tendency that and is linier to r of those wood. is approximately
2 times greater than its. The number of
nail (4-10 pieces) did not give effect of average Z, but with the nail diameter
4.1 to 5.2 mm Z increased significantly and this value decreased on 5.5 mm
diameter nail. Average Z also increases with increasing of ρ for displacement 1.50 mm (Indonesian Standard
PKKI NI-5 1961)) and 5.0 mm (breaking load). The increasing of Z happens
because ρ effect. At 5.0 mm displacement the increase of Z is not as sharp as
that of 1.5 mm. Power regression type is the best equation to predict Z of wood
density for several diameters of nails.
Keywords: Allowable load of
tensile parallel to grain, density, displacement, double shear connection,
lateral design values
