PENGARUH DIAMETER DAN JUMLAH PAKU TERHADAP KEKUATAN SAMBUNGAN GESER GANDA BALOK KAYU NANGKA (Artocarpus heterophyllus) dan RASAMALA (Altingia excelsa Noronha) DENGAN PELAT BAJA
Abstract: The application of
nail connection for part of the structural construction in Indonesia is still
become the main choice. Connection type that must be counted on seriously for
structural construction, are tension, shear and momen connection. Nangka wood
is a type of woods that available in sawing or community woods work around
Bogor. Rasamala is endemic and unique woods from West Java. Nails as connection
are cheap, available and workable. This research objective is to investigate the
effect of diameter and amount of nails to double shear connection strength on
two type of woods. The results showed that the increase of diameter and amount
of nail will rise the capacity of total allowable load per shear plane (RT) or
double shear connection strength of nangka woods and rasamala-steel plate, but
this phenomena is different for allowable load capacity per nail per shear
plane (R) for both of that type. Design value for nangka wood based on diameter
size 4,1; 5,2 and 5,5 mm are 261; 358 and 365 kg respectively, and for rasamala
wood the design value is sligthly low, which is 227; 311 and 321 kg
respectively. The minimum value becomes fundamental for determining design
value of total allowable load per shear plane connection (RT) based on amount
of nail (4-10), which is determined by multiply the value of certain type woods
with amount of nails used.
Key words: double shear,
displacement, allowable load per nail per shear plane (R), total allowable load
per shear plane (RT)
