Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the
Demolition Contractor Works from the Top Down to Demolish 12-Story D.C. Building Florida-based demolition contractor brings down 12-story structure in the heart of Washington D.C. October 17, 2017
Mar 15, 2020· This was followed by the concrete compression crushing and the compression buckling of top GFRP bars that caused slabs S1 and S2 to fail completely. More severe concrete crushing through the depth was observed in slab S2 when comparing with S1, as shown in Fig. 5(a) and (b). This indicates the holes in slab S2 collapsed at the time of ultimate
This report presents the results from an experimental and computational study of two reinforced concrete beam-column assemblies. NIST developed the test plan and designed the specimens. The specimens represent portions of concrete moment frame buildings designed for Seismic Design Categories C and D, respectively.

The stiffness degradation damage due to the compressive crushing d c is . (2014), the researchers designed a series of planer one-story one-bay reinforced concrete frames upon ACI 318M-14
Feb 29, 2016· During earthquake, reinforced concrete walls show complicated post-yield behavior varying with shear span-to-depth ratio, re-bar detail, and loading condition. In the present study, a macro-model for the nonlinear analysis of multi-story wall structures was developed. To conveniently describe the coupled flexure-compression and shear responses, a reinforced concrete wall was idealized with

Indian construction industry, especially in the past few years, is evolving through a phase of transition towards modern innovative construction methods. Constraints in land utilization and challenges in the real estate industry resulted in finding ways for more effective space utilization leading to the change of focus from horizontally distributed to vertically distributed structures
A device for breaking and crushing reinforced concrete and also shearing off steel bars or the like embedded therein or exposed therefrom after concrete has been torn off. The device comprises in general a frame, a cutter assembly or unit and a hydraulic actuator for operating the cutter assembly. The cutter assembly comprises a stationary cutting blade securely attached to the frame and a
Jul 01, 2007· However, full scale fire tests on reinforced concrete flexural members are time-consuming and very costly to perform. Thus, in an effort to elucidate potential differences in the structural behaviour of FRP-reinforced concrete slabs during fire as compared with steel-reinforced slabs, a relatively simple numerical model has been developed.

The story drift of a building provides valuable information about its structural behavior under seismic loads. These could cause large horizontal deformations and even instabilities. Some standards therefore call for a check of the stroy drift in its center of gravity. It indicates, for example, if a second-order analysis ((P-Δ effect) is necessary.
The 3-story parking garage was an unbonded tendon, post-tensioned reinforced concrete structure. The post-tensioning insinuated itself structurally into the lower three floors of the 33-level tower that was a post-tensioned/cast in-situ reinforced concrete hybrid structure.
Aug 10, 2020· With the additional screening system, it will enable us to broaden our services which means crushing and screening on-site. We will use the screen system mainly for production of 0-16 and 0-32 final product. Sporadically, the R1100S, will be required for recycling demolition debris such as reinforced concrete as well as asphalt,”
Jun 03, 2019· The paper aims to develop theoretical expressions for the ductility design of very-high strength concrete (VHSC) (> 100 MPa) columns using curvature and a new flexural energy-based ductility approach. Eventually, the study aims to evaluates the feasibility of VHSC columns for different ductility classes, considering the limitation of providing a higher volume of transverse reinforcement
