PERFORMANCE BASED DESIGN
The concept of achieving design with some focus on performance is not new, the tools and methods that changes. To discuss performance for design, it is important to classify and separate its functions and features. If a building consists of a set of parameters, the design process can be associated to a balance act, where parameters are weight and arranged to fit the context of a project.
In traditional architectural design, the use of measurable parameters often postponed or take place in a later phase of the design process. The concept design is rather focused on aesthetics, plan functionality and experience of spaces, however, this approach limits the success of an integrated solution.
Today, there is an almost understood association with computational tools along with the measurable parameters and thresholds. The massive power of computation makes it superlative for repeating calculations, it could be useful in optimization algorithms for instance, and the target parameters for the optimization have to be simple enough to be expressed in a computer algorithm. In the application of structural engineering, these quantifiable and measurable parameters could be mass, force, moment, deflection or even cost.
Karamba plug-in for Rhinoceros 3D software is a physics engine and a good example of an interactive, parametric finite element program that helps analyzing the responses of shell structures and 3D beams under arbitrary loads. The software is used in
There are 25 major specialties in engineering that are recognized by professional societies. In any one of those 25 specialties, the goal of the engineer is the same. The goal is to be able to come up with a cost effective design that aids people in the tasks they face each day. Whether it be the coffee machine in the morning or the roads and highways we travel, or even the cars we travel in, it was all an idea that started with an engineer. Someone engineered each idea to make it the best solution to a problem. Even though engineer 's goals are similar, there are many different things that engineers do within their selected field of engineering. This paper will focus on the architectural field of engineering.
The goal of the beam project is to design and construct a beam that can hold a given amount of weight without breaking. The beam is required to hold a concentrated load of 375 lbf on the X-axis and 150 lbf on the Y-axis. The maximum allowable weight of the beam is 250 grams. The maximum allowable deflection for the beam is 0.230 in. and 0.200 in. for the X and Y-axis respectively. The beam is required to be 24 in. in length, and it will be tested on a simply supported configuration spanning 21 in. All calculations are to be done under the assumption that the density of basswood is 28 lbm/ft3 and the modulus of elasticity for basswood is 1.46x106 lbm/in2. Given the constraints of a spending cost of $10.50, a maximum beam weight of 250 grams,
With modern computational methods, most notably finite element analysis, designers are now able to simulate the response of a structure under a multitude of highly complex loading conditions. Another important aspect of these tools are their ability to solve ever increasingly complex problems in a faster time than ever before. These advanced computational tools also allow engineers to optimize designs much faster. These new optimal designs will improve the strength and stiffness of structures and lower their weight. This will not only improve a design's performance, but also help improve efficiency. These abilities are very exciting since they allow for a more fully developed and accurate picture of a structure's performance evident even in the most demanding
Interior design and architecture are essential, and often overlooked, aspects of everyday life. In modern society people rely on function, durability, and visual appeal when selecting designs for their homes, businesses, and places of leisure. The way that a space is designed influences such things as mood, which, in the case of a business, can impact the productivity of employees and either draw or repel customers. In residential design, the design becomes very personal and, to be considered a successful design, must properly reflect the home owner while at the same time offering some practicality that makes the space livable. An effective design, for any space, must solve some problem, be it function, flexibility, or some other criteria. Simply solving a problem would not please the customer, however, unless it offered some visual appeal. Creating function with style is the real job of any interior designer, and is essential in a content society.
Each separate truss (of the dimensions 920x5x50mm) consisted of a Pratt truss with nine diagonal members on each side of the centre. The model was tested in sufficiently isolated condition by tutors. It successfully passed the initial weight test, and satisfactorily resisted horizontal forces. Once fitted onto the testing rig, loads were applied and increased incrementally. Slight deformation was observed before failing at 12.5 kg, at which force a collection of members failed in succession, concluding the test.
One thing that has been brought up as a concern for the hospital is using unistrut versus structural steel to hold booms from the ceiling. Unistrut tends to move too much and causes too much movement in the booms when doctors are in surgery. The engineer on the project has started to investigate this problem and has agreed to use structural steel instead of unistrut. In my Structural Systems I class, we learned how structural steel deflects with certain

The design process itself runs through a systematic and interactive methodology to create an innovative and functional design solution whereby the needs and resources of the occupants are satisfied.
Styles can truly help throughout the design stage, especially with the concept part. For this proposed project, two schools have been chosen to incorporate and follow, these two schools are the International Modern Architectural School and Sustainable Modern School.
As an aspiring Architectural Technologist I will be expected to possess a variety of skills which are valuable for any Architectural Technologist position. I will be studying and evaluating a building design of the Engineering and Computing Building, Coventry. I am to assess the structure, identifying, why the building was designed in the way it was, the impact, challenges and purposes. This will allow me to understand the integration of architectural and structural design.
The book, Sensory Design published by Joy Monice Malnar and Frank Vodvarka in 2004, explores a new multi-sensory method of design for architects in 335 pages. The opening of the book starts with a question “What if we designed for all senses?” Very similar to articles from Pallasmaa, the book leaves the reader wanting to know more about this method although this book covered many topics and included many references. Malnar is an associate professor at the University of Illinois, and Vodvarka is an artist who wrote many articles on architectural history.
Visual Basic Application (VBA) in MS Excel is used to develop an interface with STAAD.Pro software to perform Geometrically Nonlinear Analysis of truss systems.
Most of the problems in engineering are governed by differential or integral equations. An exact solution can be studied by solving these equations. However, complexities in geometry, material properties and in the boundary conditions that are seen in the most real world problems usually mean that an exact solution cannot be obtained in a reasonable amount of time. Current product design cycle time shows that the design solution should be obtained in short of time. The solutions thus obtained are approximate solutions. FEM is one such
However, modern sustainability initiatives call for an integrated and synergistic design to both new construction and in the retrofitting of an existing structure. Also known as sustainable design, this approach integrates the building life-cycle with each green practice employed with a design-purpose to create a synergy amongst the practices used.
The finite element method is a numerical technique that has been successfully adopted to study special cases where, for instance, stress-strain distribution is required. In the past, due to the complexity of the problems, it was difficult to describe them in the same manner because they took much time and effort. However, the development and the use of sophisticated software have now improved this situation. (Zienhiewicz, 1977)
