Water tank is used extensively for storing water, inflammable liquids and other chemicals. Generally, to provide water at large, tank is supported on frame or shaft (a vertical cylindrical shell). The staging with a single row of columns placed straight (vertical) along the periphery of circle or shaft, are generally adopted for elevated water tanks to support the tank container. Apart from ver...

In most of the designs of rigid structural frames, the analysis is carried out by assuming fixity at base, which means that the building is idealized to rest on hard rock. This paper discusses the importance of considering the effect of soil stiffness on the seismic performance of rigid structural frame system resting on it. Flexibility of soil causes lengthening of lateral natural period of th...

Deployable structures are structures that can change shape from a compact to an expanded form. Thus, their advantage over conventional structures is adaptability, whether in the sense of adapting to changing environmental conditions or being adapted for repeated transportation and deployment. These features make deployable structure highly desirable for a wide range of applications in the aeros...

Different kinds of meta-heuristic algorithms have been recently utilized to overcome the complex nature of optimum design of structures. In this paper, an integrated optimization procedure with the objective of minimizing the self-weight of real size structures is simply performed interfacing SAP2000 and MATLAB softwares in the form of parallel computing. The meta-heuristic algorithm chosen her...

This study aims to compare structural modeling with the addition of wall elements and without walls help SAP2000 software. The method used in this is time history analysis using San Fernando groundmotion data. Based on that has been done, participation variance mass reached 90% for structures mode 278 while 243. resulted a decrease drift value. average percentage settlement each floor 40.12% X ...

braced frames structures have a good lateral stiffness against earthquakes. however, energy loss of their members is slight and strong forces are given to the structures. moment frames have a more flexible function against earthquakes and also have a better flexibility than braced frames. however, since its lateral stiffness is low, too much displacement of the structure results in an increase ...

Need for designing certain important structures to resist blast loads is increasing in the recent past years, due to the enhanced terrorist operations. A bomb explosion can cause very serious damage on the building's external and internal structural frames. Collapse of one structural member in the vicinity of the source of explosion, may then create critical stress redistributions and lead to c...

The objective of the present paper is to illustrate the use of the commercially available mathematical package MAPLE and other computer software for educational purposes. The problem chosen to illustrate the use of the software is the problem of forced vibrations of an elastic plate. The presentation of the topic is made in a simple manner to make it suitable for introductory graduate or underg...

To protect the non-structural components in critical facilities (such as hospitals), focusing in particular on the key sensitive components on the floor of a room, the combined solution of stiffening the structure and isolating the floor is proposed. One-story and three-story stiffened shear frames were considered as examples for the purpose of conducting different analyses. Models for each ana...
