Implementation of wood structure engineering policy in Indonesia

Bambang Sudaryana

Abstract: 

In wooden buildings, the collapse is generally due to connections or relationship that does not meet the standards. And structural system is not earthquake resistant. Wood Regulation in Indonesia is very outdated, since 1961 Indonesian Wooden Regulation (PKKI 1961) 52 years has not changed. Several draft wood regulations of 1980 and 2002 were made until the issuance of SNI 7973: 2013 Design specifications for timber construction. Currently, the regulations abroad use both Load and Resistance Factor Design (LRFD), and Alowable Stress Design (ASD) design methods, Breyer 2008. PKKI 1961 uses the old ASD way. In SNI 7973: 2013 which adopts NDS 2012, it contains both LRFD / DFBK and ASD / DTI and both are usable in design. The lessons that are learned from structural failure caused by the earthquakes are raising concerns about the weak knowledge about theory, analysis and standards of good building design. Experience in buildings with concrete and steel shows that in general the failure is caused by; Soft story mechanism, short column effect, pounding, excessive time, lack of longitudinal reinforcement and shear, no reinforcement on beam and column relationships and reinforcement detailing such as stirrup, crooked and overlap reinforcement requirements. It may be indicated that existing standards are unknown or followed by the requirements or even inadequate. From experience in earthquake-affected areas, wooden buildings show good resilience to earthquakes even though they are non-engineered buildings. Wooden buildings are generally more resistance to earthquakes. It is because their light mass resulting in small inertia force of earthquake with a large strength / mass ratio
