Which of the following is the primary purpose of a gusset plate used in steel structure connections?
Which of the following is the primary purpose of a gusset plate?
Gusset plates are used in joint, bend or otherwise disjointed structural locations that require additional support to withstand stresses.
Which of the following is a basic property of steel quizlet?
Terms in this set (10) Which of the following is a basic property of steel? It is the strongest of the common building materials.
Which of the following are the points where inclined members intersect the vertical members in a steel rigid framed building with a gabled roof?
The point where inclined members of a gabled rigid frame intersect the vertical members is called the knee. Trusses that are frequently used in three-dimensional space frames are known as delta trusses.
Which of the following structural members require less heat to reach the failure temperature?
Heavy steel beams and girders frequently remain in place under severe fire exposure because steel: is a heavy material and a good conductor of heat. has a high density and is a poor conductor of heat. requires less heat to reach the failure temperature.
What is the purpose of the gusset?
The reason for the pocket is simple: A small piece of fabric—called a gusset—sits in the crotch of your panties to provide reinforcement, breathability, and moisture-wicking.
What is the purpose of a gusset plate quizlet?
Wooden or metal plate used to connect structural members that are butted together; most often used in the construction of trusses. Many metal gusset plates are simply pressed into the wood and are subject to early failure if the plates warp from the heat of the fire.
Which of the following materials is commonly used as coarse aggregate as part of a concrete mixture?
Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel.
Which type of concrete reinforcement uses steel bars that are placed in the formwork before the concrete is poured?
Which type of concrete reinforcement uses steel bars that are placed in the formwork before the concrete is poured? water-to-cement ratio. Which of the following statements is MOST accurate regarding the fire-resistance of concrete assemblies?
Which of the following is a layer of material that is installed outside of the studs?
Which of the following is a layer of material that is installed outside of the studs to provide structural stability, insulation, and an underlayer for siding? a wood panel product. 19 percent or less.
Which of the following footings is a continuous strip of concrete that supports a wall?
A wall footing or strip footing is a continuous strip of concrete that serves to spread the weight of a load-bearing wall across an area of soil.
Which of following are the functions of the roof ballast?
The ballast is used to keep the roofing system cool and of out of the sun’s harmful rays, thus keeping energy costs down. The gravel top coat is also extremely resilient to heavy foot traffic and high-wind scenarios.
Which of the following statements regarding the significance of the surface to mass ratio of wood in fire fighting is most accurate?
Which of the following statements regarding the significance of the surface-to-mass ratio of wood in fire fighting is MOST accurate? A greater surface area for a given mass of wood permits a more rapid combining of fuel and air for combustion.
What is the mesh wire size used for screening the coarse aggregates in performing the specific gravity and absorption?
6.3 mm mesh
Apparatus Required
A wire basket of not more than 6.3 mm mesh or a perforated container of convenient size with thin wire hangers for suspending it from the balance.
Why does the sieve analysis of coarse aggregate should be conduct before it use in mixing concrete?
Performing a sieve analysis is important when analyzing materials because their particle size distribution can affect a wide range of properties such as the strength of concrete, the solubility of a mixture, their surface area properties and even their taste.
Why is coarse aggregate used in concrete?
Aggregate materials help to make concrete mixes more compact. They also decrease the consumption of cement and water and contribute to the mechanical strength of the concrete, making them an indispensable ingredient in the construction and maintenance of rigid structures.
Why is steel rebar used in concrete?
Rebar makes concrete several times more resistant to failure. It provides tensile strength using a reinforcing bar that is resistant to corrosion. If you want to make your concrete structural, rebar provides much stronger support than steel wires, reinforcing fiberglass and many other products on the market.
Why steel and concrete are used in conjunction in reinforced concrete?
In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans.
What type of steel is used in reinforced concrete?
Rebar Steel
More commonly known as reinforcing steel, this type of steel is used as a tension device for reinforced concrete or reinforced masonry structure. It is created out of carbon steel, with ridges given to it for mechanical anchoring in a better way in the concrete.
What type of steel is used for structures?
The most common among the most common steel types in construction is definitely mild steel type, also known as plain carbon steel. Carbon steel is a type of steel that contains between 0.12 and 2% of carbon, which is the main alloying constituent.
Which of the following types of steel is most commonly used for structural steel?
Carbon Steel. The most commonly used steel in construction projects in the United States is carbon steel. In fact, 90% of the steel made in the U.S. is carbon steel.
