Reinforced concrete building design project & project based learning / Ahmad Sharul Saharudin

In designing process, both manual and software calculation come out with different output. Almost of this case is because of different method or formula were applied into the calculation. For example, manual design use summation moment method, Shear Force Diagram (SFD) and Bending Moment Diagram (BMD). But, the software that we used, PROKON, use Wood- Armer formula to compute the moment. From this, it will give the different result. However, there is have the method to comparing the output between manual calculation and software calculation that I applied in this project. The method is the percentage different between software output and manual output must under 30%. This percentage range I assumed acceptable. For percentage range more than 30%, it considers as risk to be apply for these two storeys - house project.
During the process of designing, can't be deny that error can be happen such as using wrong design parameters, apply wrong formula, consider wrong case for structural element such as slab which have its case according to their continuous edge. No matter how, as the student which still a beginner in designing, we will keep improve our skill in design also with the software. At last, we are managed to do both manual and software
design correctly. Hence, we have to master's in design calculation also must have deep understanding with the formula uses before we start the design process. This to make sure that the structure that we design is surely safe and last to the proposed design life. In addition, the design that be proposed must cost - effective follow the aspect in UBBL design rules. This is to save project cost at the same time achieve the requirement of the project.
