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...

Purpose: To compare in vitro fracture resistance of endodontically treated premolars restored with bonded amalgam or resin composite. Materials and Methods: Fifty intact and caries-free premolars that had been extracted for orthodontic treatment were selected. All teeth were subjected to endodontic procedures and MOD cavity preparation. They were then randomly divided into the five following gr...

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,...

objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...

the structural and energetic characteristics of o3–h2o complexes have been investigated by means of b3lyp, mp2, mp4(sdtq), ccsd(t) and qcisd(t) methods in conjunction with the aug-cc-pvdz and aug-cc-pvtz basis sets. six conformers were found for the o3–h2o complex. two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional o∙∙∙h hyd...

Two series of banana-shaped liquid crystalline (LC) H-bonded complexes HPm/CBn (i.e., bent-core H-bonded sidechain homopolymer HP mixed with bent-core covalent-bonded small molecule CB) and CPm/HBn (i.e., bent-core covalent-bonded side-chain homopolymer CP mixed with bent-core H-bonded small molecular complex HB) with various m/n molar ratios were developed. The bent-core covalentand H-bonded s...

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...
