PART-A
ans all the qestions
10x2=20marks
1.Define safe bearing capacityof soils.
2.Write any 2 functions of a good foundation.
3.Define deep foundations.
4.What are rules for good bonding?
5.What are the 2 kinds of stone masonry?
6.state any four requirements of a flooor.
7.Define poison's ratio.
8.Write the relation connecting the 3 modulli of elasticity.
9.What is a T-beam slab.
10.What are the functions of doors and windows?
PART-B
ans any 3 qestions
3x10=30marks
11.Describe any four kinds of foundations you have learned with neat sketches.
12.What are the precautions to be observed during the construction of brick masonry?
13.Write short note on a) kinds of lintels b) NBC Classification of buildings.
14.The subsequent readings were recorded in a test conducted on a steel rod of 10 mm diameter and
gauge length 200 mm
Extension under a load of 25kN =0.25mm
Yield load =30kN
Ultimate load =60kN
Breaking load =50kN
Length of the rod after failure =240mm
Diameter after failure =16mm
calculate Young's modulus of elasticity,stress at yield point and ultimate point,Nominal and actual stress at breaking point,% elongation and % reduction in area of cross part.
15.A load of 300kN is acting on a R.C.C column of size 250mm x 250mm. The column has been reinforced by four steel rods of diameter 25mm every. Young's modulus of steel is 14 times that of concrete. compute the values of stresses developed in steel and concrete and load shared by concrete and steel.
16.What are the norms to be followed while fixing doors and windows.
