Understanding Structural Systems

Systems : Various definitions

A set of connected things or parts forming a complex whole.

A set of things working together as parts of a mechanism or an interconnecting network

A system is a set of interacting or interdependent components forming an integerated whole or a set of elements (often called components) and relationships which are different from relationships of the set or its elements to other elements or sets.

Systems: various definitions

A system is a collection of components wherein individual components are constrained by connecting interrelationships such that the systems as a whole fulfills some specific functions in response to varying demands.

What do we mean by Physical laws?

A physical law or scientific law according to the Oxford English dictionary is "a theoretical principle deduced from particular facts, applicable to a defined group or class of phenomena, and expressible by the statement that a particular phenomenon always occurs if certain conditions be present."[1] Physical laws are typically conclusions based on repeated scientific experiments and observations over many years and which have become accepted universally within the scientific community.

Understanding physical laws

Physical laws are: True, at least within their regime of validity. By definition,

there have never been repeatable contradicting observations.

Universal. They appear to apply everywhere in the universe. Simple. They are typically expressed in terms of a single

mathematical equation.

Understanding Physical Laws

Absolute. Nothing in the universe appears to affect them. Stable. Unchanged since first discovered (although they may have

been shown to be approximations of more accurate laws. Omnipotent. Everything in the universe apparently must comply

with them (according to observations Generally conservative of quantity. Often expressions of existing homogeneities (symmetries) of space

and time. Typically theoretically reversible in time (if non-quantum),

although time itself is irreversible.

Understanding Physical Laws

Some of the more famous laws of nature are found in Isaac Newton's theories of (now) classical mechanics, presented in his Philosophiae Naturalis Principia Mathematica, and inAlbert Einstein's theory of relativity. Other examples of laws of nature include Boyle's law of gases, conservation laws, the four laws of thermodynamics

Example of systems

Physical systems : machines, springs computers, structures solar system/water cycle system etc.

Social systems : legal system etc. Educational system Admission system Examination system Biological systems Digestive system Respiratory system Manufacturing/Production system Eco system etc.

Understanding System

System has a structure ( It contains parts or components) that are directly or indirectly related to each other.

System has a behavior . It contains processes that transforms input in to output.

System has inter connectivity . The parts and processes are connected by structural and/or behaviour relationship.

There may be sub systems in a system

What is Structure? Dictionary meaning?

Something made up of a number of parts that are held or put together in a particular way: hierarchical social structure.

The way in which parts are arranged or put together to form a whole; makeup: triangular in structure.

The interrelation or arrangement of parts in a complex entity: political structure; plot structure.

Something constructed, such as a building. Biology

a. The arrangement or formation of the tissues, organs, or other parts of an organism.

b. An organ or other part of an organism.

Structural System

In building Construction the particular method of assembling and constructing structural elements of a building so that they support and transmit applied loads safely to the ground without exceeding the allowable stresses in the members.

The term structural system or structural frame in structural engineering refers to load resisting sub system of a structure. The structural systems transfers load through interconnected structural components or members.

Structure can be described as a collection or assemblage of materials that, when joined together, will withstand the loads and forces to which they are subjected. These loads are not confined just to the weight of the building itself, but will also include such forces as wind & earthquake
