What is the economical span range for the king post truss?

Free 20 Questions 20 Marks 18 Mins Explanation: (i) A queen post is a tension member in a truss that can span longer openings than a king post truss. (ii) A king post uses one central supporting post, whereas the queen post truss uses two. Even though it is a tension member, rather than a compression member, it is commonly still called a post.

(iii) King Post Truss – Span length is in the range of 5 to 8 meters. (iv) Queen Post Truss – Span length is in between 8 to 12 meters. (v) Pratt Truss – Span length is in between 6 to 10 meters. (vi) Howe Truss – Span length is in between 6 to 30 meters. Last updated on Oct 6, 2022 National Hydroelectric Power Corporation (NHPC) has finally released the result for NHPC JE (Junior Engineer).

What is termed as the inclination of roof?

Collar Roof

Pitch : It is the inclination of the sides of a roof to the horizontal plane. It is expressed either in terms of degrees (angles) or a ratio of rise to span.

What is the economical span?

Free MPSC AE CE Mains 2019 Official (Paper 1) 100 Questions 200 Marks 120 Mins Concept : The span of the bridge for which the total cost of the bridge is minimum is called economic span. Let, the ratio of cost of one span ‘S’ to cost of one pier ‘P’ be R (i.e.

  • R = S /P).
  • Then, The overall cost of the considered bridge be – C = nS + (n – 1) × P Putting S = RP C = n (RP) + (n-1)P Where, n – Number of spans (n – 1) – Number of piers For C to be minimum, dC / dn = 0, ⟹ PR + (-1) × P =0 ⟹ R = 1 Hence, S = P Hence, Economical span is one for which the cost of one span is equal to one pier.

In other words, Economical span is defined as that span for which the total cost of the substructure is equal to the total cost of superstructure. Last updated on Oct 11, 2022 The Maharashtra Public Service Commission (MPSC) has released new notification for MPSC AE Recruitment.

What is the maximum span of beam without column?

What are the Factors Controlling the Distance Between RCC Columns? –

There is no definite rule for determining the distance between two reinforced concrete columns.The load of the structure plays a crucial role and may impose specific maximum spacing. Sometimes, the client has a demand for a particular measure of spacing.Generally, architectural engineers specify the spacing between two columns based on the function of the building.Architectural engineers want to have the largest possible spacing for aesthetic reasons, whereas structural engineers are concerned about the structure’s integrity.Increasing the spacing between columns leads to an increase in the cost of the building because the increase of span of columns requires an increase in beam depth and column dimension to support larger loads. Consequently, larger columns and beams are required to withstand the imposed loads.It is better to arrange columns in a grid pattern.The distance between two reinforced columns ranges between 3-4 m for small buildings and 6-9 m for sizable facilities where large columns and free spaces are required.For ordinary structures, a distance of 5 m is appropriate, and the maximum span is 7.5, while the minimum is 2.5 m.It should be known that any distance between two columns can be used, provided that the structure’s safety and integrity are not endangered. If a designer wants to set a long span between columns, and the load is large, the column’s size needs to be increased to cope with such imposed load.
