There are two steel I beams in a construction cite. The I beam A has 3" long stringer in the middle of the beam in the center of shear web and the second beam (beam B) has multiple edge cracking (0.1" deep) due to improper rolling process in the same middle area as beam A in both top and bottom flanges. As an engineer discuss which of the discontinuities will be more likely to be considered as a defect? Why?

A retaining wall has a stem height 8.5m and width is 0.5m from top and 1.4 from below. The base is 7.0x1.5m. the toe is 1.8m and the heel is 3.8m. the backfill is inclined by 15^o. Ɣ=18KN/m³ and Φ=25

Find if the given retaining wall is stable against sliding and overturning or not. Ɣ concrete = 24KN/m³. δ = 0.6 ɸ

Q4: Experiments were conducted to determine the safe buckling load on columns with T-section 100 mm × 100 mm × 10 mm with different support conditions. When both ends of the columns are fixed, safe crippling load carried by the column was found to be 60 × 103 N. Suggest the length for other three columns for the same crippling load when the support conditions are changed to one end fixed but the other end free, both the ends hinged and one end fixed but the other end hinged. The cross section of the column is kept constant in all cases, and E = 200 GPa. Take factor of safety = 4. Instead of T section, a hollow column of same material having length 5 m and external diameter of 55 mm when subjected to a compressive load of 60 kN, there was a shortening in the length of the column by 0.120 cm. Suggest a suitable value for the thickness of the column to withstand the safe crippling load when one end of the column is fixed and other end is free?

Please define streamline, streakline, and pathline (illustrations welcome):

Q2: For analyzing a structure, shear force and bending moment diagrams were plotted for a simply supported beam of span 8 m when subjected to a uniformly distributed load of ‘w’ kN/m over a length of 4 m from the left end support, a point load ‘2.4 w’ kN at a distance 6 m from the left end support and another uniformly distributed ‘0.6 w’ kN/m at a distance 2 m from the right end support. It was noted that the magnitude of shear force at distance 4 m from the left end support is equal to (-12.5 kN). Suggest a suitable value for ‘w’ based on the given data. How it will change the reactions at the supports, shear force and bending moment values. By plotting bending moment and shear force diagram for the beam briefly conclude the relationship between the values for shear force and bending moment.

Compute |A|, the determinant of A (note: rounding errors during computation may cause Matlab to return a value like 6.2137e-16 in place of 0; in such cases, write 0 as your answer; though not necessary, you can verify the answer by computing the value of the determinant by hand). State the Matlab function you use to compute the determinants.

Using 7/8 in diameter ASTM A325-N bolts in standard holes and E70 electrodes. Design a bolted flange-plated FR moment connection between a W12×50 beam and a W14×90 column flange (RD = 15 kips; MD = 60 kip-ft) and (RL = 30 kips; ML = 120 kip-ft). For shear plate use three bolts:

(I) Check the beam available flexural strength

(ii) Design single-plate web connection

(iii) Check the connecting elements rupture strength at welds

Sketch the connection.

Question 1. a) Modern Methods of Construction (MMC) is a term which has been commonly applied to construction activities. Using your own words supported by references, provide an explanation of MMC and detail the technical construction procedures classified as MMC and explain how these differ from traditional construction
