1. Design of Tension Members

Image
A member that supports axial tension loads is defined as a tension member.  Tension members are simple structural elements to design, with perhaps the simplest being concentrically loaded uniform tension members, as they are nominally in a state of uniform axial stress. However, a tension member is not always connected concentrically. In many cases the fabrication of tension members is simplified by making their end connections eccentric, but this will induce bending   moments which interact with the tensile loads leading to a reduction in the ultimate strength.   The effect of the bending action caused by eccentric connections is dealt with in AS 4100. by introducing a correction factor  k t .   AS 4100 provides two criteria which a tension member must meet:  (i) yield :  The stress at which steel begins to deform  plastically  (permanent deformation starts). Up to this point → deformation is  elastic  (returns to original shape wh...

  In this activity, I want you to   share your learning and reflections   in the   comment section below . Don’t worry about being 100% correct — this is all about   exploring, practicing, and expressing your own understanding . 👉   How to participate: 1.      Read or watch short videos on the questions given. 2.      Answer the questions in your own words. 3.      Add links to resources you reviewed. 4.      Post your answers in the   comments below this blog . Now  Let’s research and answer laboratory shear strength parameters!!!  💡 Mohr’s Circle 1.   In your own words, what do you understand by Mohr’s circle after reading/watching videos? (Tip: Think about how it shows stresses in soil). Also, paste link you reviewed. 2.     Draw a rough sketch of Mohr’s circle and label   at least two things   you learned (example: principal str...

5.1 Settlement: What It Is and How Much Is Acceptable

Image
Settlement of Soil ·       When a soil mass is subjected to a compressive force, like all other materials, its volume decreases. ·        The property of the soil due to which a decrease in volume occurs under compressive forces is known as the  compressibility of soil. ·        The decrease in volume of soil, under stress is because of: o     Compression and Expulsion of Pore Air. o     Compression and Expulsion of Pore Water o     Gradual readjustment of clay particles into more stable configuration. ·        Reduction in volume of soil mass results in change of lateral and vertical dimensions of soil mass. ·        As soil being infinitely large in the lateral direction, hence the change in dimension in this direction is considered to be negligible, but there is significant change in vertical...
