Shear strength

the shear strength of steel fiber reinforced concrete deep beams without stirrups. For this 18 beams are cast. The beams are tested under two-point loading as per IS after 28 days curing. Fiber fraction is varied as 0%, 1.5% and 3%. The shear span-to-depth ratio (a/d ratio) for beams is kept as 0.60 for case-I and 0.74 for case-II. The cube compressive strength is estimated. The experimental results are compared with theoretical results obtained from empirical equations and design codes. Also the experimental results are compared with the equations put forth by the other researchers…

the Laminate Material Strength Properties was to plot Stress vs Strain (Figure 5 (a)) to find ultimate tensile strength (σUTS) and the maximum load (Pmax). Then to find Major Young’s Modulus (Ex), from the axial strain from the Axil/Longitudinal direction, was found by two points that contain a stress value and that are between 1000 µƐ and under 3000 µƐ Corrected Longitudinal Strain. Data point values are used in Tensile Chord Modulus of Elasticity equation to find Major Young’s Modulus. These…

Case Analysis 1. What are the facts in the case? John is the chief seismologist at one of the leading research facilities in North America who holds a P.H.D from one of the most prestigious university in the country. John has developed a method for predicting earthquake with 80% accuracy rate. From his investigation, he discovered that there is a 80% chance that an earthquake will occur with a magnitude of 7.3 in one of the four fault lines in southern california within two days. While three…

Is the Hayward Fault line moving the earth’s surface, and if so where is the evidence to prove it? There are various methods to prove that the Hayward Fault is creeping, and the evidence is viewable such as offset curbsides, building that are being torn apart, and cracks in the earth’s surface. The Hayward Fault is a strike-slip fault meaning it moves up, and down, thus giving us multiple locations in which the surface is affected. There are five different locations that I chose on the Hayward…

In particular, B, G, and E of hexagonal structure are expressed as follows [34]: where B, G, and E are bulk, shear, and Young’s modulus, respectively. The resultant elastic constants, bulk, shear, and Young’s modulus are summarized in Table 2. Here, it can be seen that the B, G, and E are increasing with increasing amount of Si on the A site. This could be attributed to the charge density shown in Table 1. In particular, the substitution of Al with Si increases the total charge density of the A…

rammed earth and cob [5] but the lack of scientific data and lack of experience by the mainstream construction industry in using these materials remain barriers to be overcome [6]. As earth is a heavy, low strength material, its use in construction is expected to essentially be limited to single storey walls and ground floors [7]. Earthen masonry shows low values of strength in compression and in tension and a resulting general brittle failure [8]. Therefore, an improvement of the final…

point anchors which, when set in the predrilled hole, are then tensioned to secure an anchoring device which will pull against the keyhole plate and the anchor point to secure the surface to a more competent layer. The mechanical bolts have more parts to go wrong, as well as a higher cost. The mechanical anchors have though shown to be a very reliable way to pull the unstable layer back to the competent layer. The forces are not being applied directly to the sides of the hole in its entirety,…

If done correctly, the conventional style deadlift builds the muscles of the backside, including spinal erectors, hamstrings and glutes. This causes lifters to struggle to get the weights off the floor, but makes lockout easy. One thing to be cautious of when conducting a conventional style deadlift is shear force from hyper extending the lower back. (Ez) According to a study of two male regional powerlifting champions, research showed that there were greater L4-L5 shear forces and moments in…

Blood Flow as a Casson Fluid 1 THE PROBELM This problem was chosen from Problems for Biomedical Fluid Mechanics and Transport Phenomena section 8, because of my interest in biomedical engineering. How the body works on the most fundamental chemical and physical levels is something that has always fascinated me. This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…
