The present study evaluates the utilization of shotcrete sandwich panel (SSP) infill and CFRP strips to strengthen reinforced concrete (RC) frames. To this end, a diagonal strip-infilled RC frame, an SSP-infilled control specimen (a bare frame) were examined as single-story specimens in terms in-plane seismic response. This work compared stiffness degradation, damping, cyclic lateral Also, avai...

Whereas entire houses are reported to be built by means of 3D Concrete Printing (3DCP), automated integration reinforcement is still a vastly unresolved challenge and - undoubtfully crucial requirement for widespread adoption 3DCP in construction practice. The disruptive technology opens up the chance overcome insufficiencies conventional steel its rationalised orthogonal use. This paper disclo...

Addition of sulphoaluminate expansive agent could be one useful method to reduce the shrinkage crack destruction shotcrete. While setting and hardening behavior early age mechanical strength cement pastes containing liquid accelerators may influenced by introduction (SEA). Therefore, in this work, hydration different accelerated with SEA was investigated via times measurement, test, isothermal ...

• Highlighting the correlation between load capacity and shotcrete thickness. Modelling of local variations in thickness bond strength. Verification material models for interface failure rock. Local weak zones do not have a significant impact on capacity. Fibre reinforced (sprayed concrete) is often used to support tunnels hard The should be designed carry from loose block, which assumed transf...

Terowongan adalah lubang bukaan di bawah permukaan tanah atau gunung dan dibuat mendatar. Kajian awal sebelum dibuatnya terowongan seperti kajian geologi geoteknik sangatlah diperlukan, karena dapat memberikan gambaran tentang kondisi batuan yang ada sekitar rencana tersebut. Klasifikasi massa merupakan tumpuan dasar dalam menganalisis kualitas menginformasikan daerah setempat untuk tujuan pemb...

In this study we explore the use of a novel numerical modelling approach to effect pillar reinforcement on stability. Case studies in literature indicate that tendons, strapping pillars, and shotcrete or thin spray-on liners are commonly used reinforce pillars. No clear methodology exists select type support design capacity required, however. This has led ongoing collapses some mines spite heav...
