Development of load and resistance factors for reinforced concrete structures in Turkey
In this dissertation, a study is conducted to develop a probability based load and
resistance factor design criterion for structural members considering the local
conditions of Turkey. The Advanced First Order Second Moment (AFOSM)
procedure is utilized as the probabilistic method of analysis. Various sources of
uncertainties associated with concrete compressive strength, yielding and ultimate
strength of reinforcing steel bars and the dimensions of beams, columns and shear
walls are analyzed and quantified. The resistance statistics for different failure
modes of different types of reinforced concrete structural members are computed by
using the resistance parameters within the framework of reliability analysis.
Structural load effects of dead, live, wind, snow and earthquake loads are analyzed
considering the uncertainties in these loads.
For different load combinations, the safety levels corresponding to the current
design practice are evaluated in terms of the reliability indexes for reinforced
concrete beam, column and shear wall design in flexure and shear, and also column
design in combined action of flexure and axial load. Depending on this evaluation
and the reliability index values reported from other countries, target reliability
indexes are selected for different load combinations and different failure modes of
structural members. Finally, a new set of load and resistance factors corresponding
to selected target reliabilities and levels of uncertainties are proposed for each
different failure modes of the structural members considered in this study,
separately.
