“…As mentioned in Section 2, the shear performance of HCS is determined by the web shear cracking concrete shear strength rather than the bending shear cracking concrete shear strength due to the introduction of prestress and the hollowing effect in the web, which has a relatively weak structure. To objectively evaluate this, the main influencing factors were analyzed using the experimental results of previous researchers [6,[14][15][16][17][18][19]. For comparison, 170 experimental data points were collected; these are summarized in Table 4.…”

“…Previous research has found that the evaluation of the horizontal shear strength in pushover tests, with the manufacturing method and interface roughness as variables, is significantly affected by interface roughness, orientation, and the presence of laitance [15]. Researchers also compared prior work on shear friction and analyzed key factors influencing the interface, highlighting the need to consider shrinkage and stiffness at the topping concrete-concrete surface [16]. Most researchers have evaluated the shear strength of HCSs with topping concrete in terms of interface roughness.…”

In this study, four-point load tests were conducted to evaluate the shear performance of factory-produced precast prestressed concrete hollow core slabs (HCS) assembled on-site. The test specimens were fabricated using compression molding and comprised six samples, with variables being the presence or absence of topping concrete and the shear reinforcement. According to the experimental variables, experiments were conducted using simple support beams to evaluate the shear performance and ultimate strength of HCSs. The results showed that HCSs, regardless of whether they included topping concrete or not, exhibited average values of shear strength more than 10% higher than the factored shear strength specified by concrete structure standards, confirming that these materials satisfy existing design standards. According to current standards, the overall reinforcement length should be increased to meet the minimum shear rebar placement requirements. However, the nominal shear strength of PS concrete hollow slabs exceeded the hollow design, with the ratio of experimental results ranging from 1.26 to 1.87 on average, satisfying the required performance.

“…The openings lead to many problems, including reducing the resistance, increasing the deflection, and a decrease in the stiffness of the constructor. In addition to many cracks around the openings' location, this decrease in the area of reinforcement concrete in the cross-sectional dimension may make the structural member perform in a complex behavior [1][2][3][4].…”

Sometimes there is in need to make openings in the slabs, and this greatly effects on the strength of the structural element. Therefore, this research studies the behaviour of one-way reinforcement concrete cantilever slabs and the extent of their effect and resistance. The number of openings, their location and sizes are the main parameters that have been studied. A comparison was made between four slabs with openings and a fifth reference model (solid slab). After conducting laboratory tests, differences were found in their behaviour and resistance. The decrease in the ultimate load reached 31.5%, while the deflection rate was a decrease between 3.2% and 62.7%. It was also found that the location and number of openings affected the behaviour of the slab.

Effect of short glass fiber on shear capacity for shallow wide reinforced concrete beams

Shallow wide reinforced concrete beams are used in modern buildings especially in residential building structures. According to current Egyptian Code Practice 203-2018; the characteristic of a shallow wide concrete beam is that the cross-section width (b) over the effective depth (d) ratio is greater than two and the beam depth is less than 250 mm. Without any shear reinforcing contribution, the applied shear stresses in shallow wide beams must be less than the concrete shear strength. And only concrete provides shear strength. An experimental program was conducted to investigate the contribution of short glass fiber polymer reinforcement to shear strength in shallow wide beams under shear stress. The short glass fiber polymer reinforcement ratio was the main parameter in this study. And also, the contribution of web shear stirrups reinforces against shear stresses. The experimental program consisted of five simply supported reinforced shallow wide concrete beams. Test results show that the use of short glass fiber reinforced polymer has a great effect on shear strength capacity, mode of failure, and ductility of shallow wide concrete beams.
