One
important aspect of seismic design of buildings with a dual reinforced concrete
structural system is the lateral stability of structural walls, when they face
this danger mainly due to flexural overstrain. The deep excursion in the yield
region of the boundary parts of bearing walls increases dramatically their
flexibility and since at the same time they are liable, because of the
earthquake vibration, to a reversing axial loading (tension – compression),
their lateral stability is at stake. The possibility of failure because of
lateral instability is limited significantly with the proper choice of an
adequate thickness, which is specified by (most) modern seismic codes as a
percentage of the height of the bottom storey. The current work investigates
one parameter that may be affecting the stability of structural walls. This
parameter is the diameter of the longitudinal reinforcement of the boundary
edges of load-bearing walls. It contains an experimental research that tries to
investigate the influence of the diameter of longitudinal reinforcement to the
ultimate bearing capacity of test specimens. It has to be noted that in order
to examine experimentally the influence of the diameter of longitudinal
reinforcement, test specimens of scale 1:3 simulating the boundary edges of
structural walls were used. These specimens were reinforced with the same or
almost the same longitudinal reinforcement ratios (2.68% - 2.79%) but had a
different number of reinforcement bars of varying diameter. The diameters of
bars which were used were equal to 8 mm and 10 mm. The specimens which were
compared to each other contained (apart from bars of different diameter) a
different number of bars and consequently a different way of placement of these
bars at the wall end sections.
