INTRODUCTION TO MECHANICS OF STRUCTURE
TYPES OF STRUCTURE ELEMENTS
BEAM
straight horizontal members are used generally vertical loads
TIE ROD
COLUMN
A long vertical member mostly subjected to compresive loads is called column
FRAME STRUCTURE
trusses: there are compost of slender rods
TYPES OF LOADING
DEAD LOAD
LIVE LOAD
WIND LOAD
EARTHQUAKE LOAD
TYPES OF LOAD
INTERNAL FORCE
*dead load are permanent or stationary loads which are transfered to structure throughout the live span.
*produces are reaction to provide balance to the structure
EXTERNAL FORCE
*internal forces was found on structure material to carry the load imposed
*internal forces acts opposite direction to the external force.
TYPES OF SUPPORT
GRAVITY
NEWTON"S LAW OF GRAVITATION SIMPLIFIES TO :
P=F/A OR P= dF/dA
P is the pressure (pascal Pa =1N/m2
F is the normal force
A is the area
PRESSURE
pressure is an effect which occurs when a force is applied on a surface
REACTION
both forces a equal in magnitude and opposite in direction
structural members subjected to a tensile force
