Direct Displacement Based Design Method

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

Today we see different amazing and unique structures of civil engineering, it should be noted that these are not only the structures these are wonders of civil engineering.

In continuation, we completed three trials per each of the three variating truss designs. The variation directly being the amount of vertical beams each contains. The variation in these was three controls having zero vertical beams,

From the information presented in the site investigations report (by soil and rock geotechnical engineers limited) I intend to propose a suitable sub-structure design that takes all site conditions into consideration, to ensure statutory and structural requirements are met referring to the UK Building act 1984. This act is made up of legislation that covers important factors concerning the construction process. The Building regulations known under the act are

This quantity relates loads or forces to the ensuing structural deformations. Familiar relationships are readily established from first principles of structural mechanics, using geometric properties of members and the modulus of elasticity for the material. In reinforced concrete and masonry structures these relationships are, however, not quite as simple as an introductory text on the subject may suggest. If serviceability criteria are to be satisfied with a reasonable degree of confidence, the extent and influence of cracking in members and the contribution of concrete or masonry in tension must be considered, in conjunction with the traditionally considered aspects of section and element geometry, and material properties (ACI 318,

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.

A building that was designed as a healthcare facility, may only be used for this purpose. (Dr. Tarawneh 2014)

Thin walled structures are an important part of engineering construction with territories of use becoming diverse continuously ranging from girder bridges, oil vessels to industrial warehouses , framed structures. Thin walled sections have various stresses and failure modes which can be difficult to predict. Thus structural engineers need help of computers for analysis of these structures. This has been done by using software called THIN-WALL which estimates the cross-sectional properties of the section according to the Vlasov theory. The method of input data for thin walled structure has been explained in this paper. Also the buckling analysis of the thin walled sections has been done using CUFSM which is based on the finite strip method. This method has been explained in the paper and the results the analysis have been compared with the hand calculations according to the Canadian code s-16. The results have been discussed and on basis of this review conclusions have been presented.

Most of earthquake related casualties are caused by structural collapse, and with proper design and construction practices it can be possible to mitigate the impacts of such natural disaster. Broad research has been conducted and still continue to analyze the effect of earthquake seismic loading on structural foundations. Instead of considering a separate or putative foundation behavior under normal loading conditions only, this study will focus on earthquake seismic loads effect on group of foundations, modelling simulation and testing of actual structural foundations adjacent to other irregularly distributed structural foundations under seismic load and resulting in best earthquake resistant design approach. An effort to come up with code based foundation design recommendations to resist earthquake seismic loads will be made. The study will try to cope up in understanding foundations behavior for different types (deep, shallow, etc.) and soil-structure interaction and deformation methodologies during an earthquake. Full scale modelling simulation and numerical modelling will be used.

In this paper the non-conventional reinforcement details of beam-column joint has been discussed. The non-conventional details includes using inclined crossed bars in the joint, and it can be placed as additional bars or by bending the longitudinal column’s bars. This paper first discusses types of joints, collapse of structures due to beam-column joint failure, explores some experimental studies about this type of reinforcement detail, and then the main advantages of using diagonal bars in the beam-column joint. Using diagonal bars has significant advantages for the beam-column joint: increasing ductility, affecting the

By implementing these technologies gives birth to many sub level new engineering concepts. These engineering conceptual methods now days become very important, latest practically applied fields in innovative constructions. The major problem by the conventional structures due to various aspects can be resolved by incorporating

The main objective of this project is to check and compare the seismic response of multi-storied building for different location of shear wall, so that one can choose the best alternative for construction in earthquake-prone area. Different location of shear wall in R.C. Building will be modeled in E-TABS software and the results in terms of natural period, frequency, storey displacement, storey drift, storey shear is compared.

In this study design of a few precast elements such as Hollow core floor units, RC load bearing solid wall, columns with corbels are considered. The designs are automated using semi-automation tools available in EXCEL. These are presented in the following sections.
