CE
Cebu-Bohol Bridge
The next bridge engineers!
Load testing and judging at the ELR.
RESULTS:

Winner : Group 3 (Highest Load capacity to Weight ratio 29.87)
CE32 SPAGHETTI BRIDGE BUILDING COMPETITION
Updates: 1 Group is already on its finishing touches stage and the rest is 70%-90% complete.
Display of bridges will be this Monday(Aug 10) starting 10am – 3:30pm at the Bates Building ramp area.
Judging and load testing will be held at the Engineering Lecture Room (3:30-4:30pm)
Everyone is invited to witness the judging and awarding of the winners.
In the meantime, here are some photos as of aug 4:
HYRDROLOGY CLASS VISITS PAGASA
Last Thursday (August 6), the 4th year hydrology class visited the local PAG ASA office to observe how meteorological data and forecasting are gathered and analyzed. The main objective of this visit is to further their knowledge in the measuring relevant data like rainfall, temperature, wind velocity, pressure, humidity etc.
In behalf of the CE class, I would like to thank PAG ASA for accommodating us and sharing their expertise in meteorological data gathering.

CEIVIL ENGINEERING SPAGHETTI BRIDGE BUILDING COMPETITION
My students in Strength of Materials engage themselves into a 2 month long spaghetti bridge building competition as part of their requirement in my subject. This will enable students to design and learn on their own, how to create a strong and economical bridge considering the rules given to them before the contest.

STRUCTURAL DESIGN AND ANALYSIS OF 2-1000L WATER TANK STRUCTURE (JUNE 2009)
This water tank structure is used to carry two 1000L (max) stainless water tank. One tank is placed 5 meters above ground and the other is 8 meters. The truss structure is made of angular bars.
Truss analysis (code checking, steel section selection), baseplate design, reinforced concrete column and footing design are performed in this project.
It is always interesting how structure behave when loads are applied. Here is an animation on the behavior of the steel structure under maximum loading. Deflection is scaled at 0.001 m per m.

ELASTIC PROPERTIES OF MATERIALS
To describe elastic properties of linear objects like wires, rods, or columns which are stretched or compressed, a convenient parameter is the ratio of the stress to the strain, a parameter called the “Young’s modulus” or “Modulus of Elasticity” of the material. Young’s modulus can be used to predict the elongation or compression of an object as long as the stress is less than the yield strength of the material.

- 1 N/m2 = 1×10-6 N/mm2 = 1 Pa = 1.4504×10-4 psi
- 1 psi (lb/in2) = 144 psf (lbf/ft2) = 6,894.8 Pa (N/m2) = 6.895×10-3 N/mm2
Note! Use the pressure unit converter on this page to switch the values to other units.
Strain
Strain can be expressed as
strain = dL / L (1)
where
strain = (m/m) (in/in)
dL = elongation or compression (offset) of the object (m) (in)
L = length of the object (m) (in)
Stress
Stress can be expressed as
stress = F / A (2)
where
stress = (N/m2) (lb/in2, psi)
F = force (N) (lb)
A = area of object (m2) (in2)
Young’s Modulus (Tensile Modulus)
Young’s modulus or Tensile modulus can be expressed as
E = stress / strain = (F / A) / (dL / L) (3)
where
E = Young’s modulus (N/m2) (lb/in2, psi)
Elasticity
Elasticity is a property of an object or material which will restore it to its original shape after distortion.
A spring is an example of an elastic object – when stretched, it exerts a restoring force which tends to bring it back to its original length. This restoring force is in general proportional to the stretch described by Hooke’s Law.
Hooke’s Law
One of the properties of elasticity is that it takes about twice as much force to stretch a spring twice as far. That linear dependence of displacement upon stretching force is called Hooke’s law which can be expressed as
Fs = -k dL (4)
where
Fs = force in the spring (N)
k = spring constant (N/m)
dL = elongation of the spring (m)
Yield strength
Yield strength, or the yield point, is defined in engineering as the amount of strain that a material can undergo before moving from elastic deformation into plastic deformation.
Ultimate Tensile Strength
The Ultimate Tensile Strength - UTS - of a material is the limit stress at which the material actually breaks, with sudden release of the stored elastic energy.
