Ultra-high performance concrete (UHPC) has been demonstrated to be a realistic alternative less maintenance and significantly longer service life due its better mechanical properties low permeability. The bond of the deformed steel bar embedded in UHPC is critically important for safety structures. This paper conducted an experimental investigation on behavior bars UHPC. impacts loading method,...

Algebraic varieties that are locally isomorphic to open subsets of affine space will be called plain. Plain varieties are smooth and rational. The converse is true for curves and surfaces, and is unknown in general. It is shown that plain varieties are stable under blowup in smooth centers.

Abstract Corrosion in reinforced concrete (RC) structures is associated with a reduction of the rebar diameter, loss interfacial bond, cracking, and eventual spalling probable collapse structure. The negative effects corrosion on structural safety, durability, longevity imposes significant costs national economy. Therefore, planned non-destructive testing (NDT) essential to enhance safety econo...

Ductile design and detailing provisions were revised in 2016 by the Bureau of Indian Standards. It introduced Strong Column Weak Beam Provision (SCWB) for beam-column joint. In this paper, an attempt is done to investigate influence SCWB provision on Longitudinal Rebar Quantity (LRQ) typical columns i.e. Corner Column, Edge Middle seismic Zones III, IV, V six-story buildings. Story-wise variati...

As a novel civil engineering material, Engineered Cementitious Composite (ECC) has attracted more and attention due to its strain-hardening characteristics, good post-cracking resistance unique properties. Bonding between rebar great effect on the mechanical behavior of structural members. In this paper, direct pull-out tests were conducted understand bond ECC rebar. The test parameters include...
