“…Figure 5 illustrates the MPC connectors. The three-dimensional eight-node solid element C3D8R [23][24][25][26] is used to model the steel beam, the concrete, and the studs, whereas the truss element T3D2 is used to simulate the steel rebar. The lines in Figure 4 are not mesh lines, but partition lines.…”

“…A hard contact was used in the normal direction, and a penalty was used with a friction coefficient of 0.45 in the tangential direction [28]. In the present study, the embedded constraint was used to model the contact between the concrete and the reinforcing rebars inside the slab [23,24,26]. Moreover, the studs were tied to the steel flange by using tied constraints in the first model.…”

Due to the shear strain in the plane of the slab, the parts of the slab remote from the steel beam lag behind the part of the slab located in its proximity. This shear lag effect causes a non-uniform stress distribution across the width of the slab. As a result, several standards have introduced the concept of an effective flange width to simplify the analysis of stress distribution across the width of composite beams. Both the computed ultimate moment and serviceability limit states are directly impacted by the effective width. The effect of using a large number of contact points as shear connectors on the effective width of a steel beam flange has not been investigated. A three-dimensional finite element analysis is carried out in this paper. The ABAQUS software (version 6.14) is used for this purpose, where several variables are considered, including the surface area connecting the steel beam and concrete slab, the transverse space, and the number of shear connectors. It was discovered that the number of shear connectors on the steel beam flange has a major impact on the effective width. The many connectors work together to provide a shear surface that improves the effective width by lowering the value of the shear lag.

“…Ordinary Portland cement (OPC) is a type of cement that is commonly utilized in concrete and mortar. It is made by heating limestone and clay at high temperatures and grinding the resulting material into a fine powder [1][2][3]. OPC is the most common type of cement utilized in various applications, including foundations, driveways, sidewalks, and walls.…”

The impact of Nanoparticles of (〖AL〗_2 O_3and 〖CaCO〗_3) particles on the features of cement mortar was explored in current research with a mean diameter of ~50nm, and 100nm in three various amounts of 1, 3, and 5% substitution by cement’s weight as binary blending materials with fixed water/cement proportion 0.46. Cement mortar's mechanical and physical features (compressive strength, density) were tested after 7 and 28 days. The findings illustrated that utilizing nanoparticles of 〖AL〗_2 O_3 improved the mortar compressive strength at early ages at 7 curing days better than 28 curing days, and 3% of substitution was the optimal proportion. Also, utilizing nano-〖CaCO〗_3 as a binary blending mixture with substitution proportion (1, 3, 5%) by cement's weight improved mortar compressive strength at early ages at 7 curing days better than 28 curing days. However, there were no apparent effects when nanoparticles of (〖AL〗_2 O_3 and 〖CaCO〗_3) were replaced on the density and ultrasonic pulse velocity of cement mortar at 7 and 28 days. The interaction impact of substitution 1 and 3 percent of nanoparticles of (〖AL〗_2 O_3 and 〖CaCO〗_3) particles to cement mortar increased the CS by (28 and 74%) at 7 curing days and (30 and 42%) at 28 curing days, respectively.

“…Due to the availability of its base constituents, economy, strength, and flexibility, reinforced concrete is usually preferred more than steel, timber, and masonry in building construction. However, from a design and structural perspective, RC is not a simple composite material as it comes to mind (Ali et al, 2022;Hamad et al, 2021;. On the contrary, it is a complex material that provides a special bond between two materials (steel and concrete) that differ in their properties.…”

The behavior of hollow-core columns composed of reactive powder concrete (RPC) contained by a circular carbon fiber reinforced polymer (CFRP) tube is investigated numerically in this work. This research used circular hollow core column samples with an outside diameter of 20.6 cm, an interior diameter of 9cm, and a height of 80cm. These examples have been created utilizing 116 MPa reactive powder concrete. Nine groupings of specimens were created. A control set of nine unconfined hollow columns with stirrups strengthened by 12mm longitudinal bars (HCRPC). Groups two through five have been produced up of RPC hollow column specimens with similar reinforcement but were externally confined with CFRP of 0.131, 0.262, 1.2, and 2.4mm thick (These thicknesses are commercially available (0.131 for CFRP one layer sheet, 0.262 for two layers of CFRP sheet; 1.2 for one layer of CFRP plate. And 2.4 for two-layer of CFRP plate) respectively, placed at mid-length of the columns. Sets six to nine, on the other hand, are identical to the previous sets, but the CFRP restriction has been put at both columns' ends. Axial load thru the column center and uniaxial loading with 2.5 and 5 cm eccentricities from the center were applied to all columns. According to the findings, CFRP confinement boosted the strength of HCRPC columns marginally.
