Methods to Determine Vertical Stress

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal component of the soil or the underground formations undergoes deformations or a tectonic shift. The amount of deformation depends upon the amount of load acting on the soil surface, which indeed, depends on the weight of everything present above the soil. Due to this, the underground soil element develops internal stresses which try to resist the tectonic changes.

buildings on a day when the temperature is 25 C. The
sidewalk is 6 m long and consists of two slabs each 3
m in length and of negligible thickness. What would
be amount of buckling (displacement) upwards that
will occur in the slabs if the temperature increases to
38 0C. Assume that the buildings don't move and the
slabs move directly upwards from the joint when they

2) The flooring system shown is composed of slab panels measuring 20 X 25 ft in plan, supported by shallow column-line beams, as shown in the figure. The slab is pre-cast and resting on the beams. The panels carry a service live load of 144 psf in addition to the self-weight of the floor. a) Calculate the factored load on beam CD as per the tributary area shown. Assume a slab thickness of 7 in and the density of the concrete used to be 150 pcf. Use the load combinations from the ASCE 7-10 load combinations for Strength Design (2.3.2). b) Sketch the bending moment diagram (BMD) for the beam using the factored load calculated in step (a). c) Calculate Mu for the trapezoidal load distribution. d) Design a reinforced concrete beam using a rectangular section to carry the Mu calculated in step (c). You can use design guides, but show clear steps. Use concrete with fc'=4000 psi and steel with fy = 60000 psi.
