Abstract. Construction progress monitoring is an important process throughout the project timeline towards its successful completion. Among imaging techniques, photogrammetry considered as economical and effective method. However, few studies can be found on construction via photogrammetry; thus, not much guideline available for this domain. This study evaluated tools assessment of rebar grid f...

Grouted sleeve connections have been widely used in precast construction for joining rebar. In order to study their post-fire seismic performance, grouted connections, which are heated first elevated temperature and then cooled down room temperature, tested under both monotonic cyclic loadings. For comparisons, the same tests also carried out on continuous The failure modes, skeleton curves com...

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,...

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...

For heavily loaded long-span (HLS) logistics buildings, embodied CO2 (ECO2) of a structural frame accounts for more than 80% the emissions entire building. To realize sustainable structure from perspective, an innovative construction method that reduces ECO2 is required. Through studies conducted over several years, we have developed SMART (Sustainable, Measurable, Attainable, Reliable, and Tim...

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...
