This research was commenced with the objective of investigating lightweight concrete LWC behavior when exposed to fire by partial aggregate replacement polystyrene foam under concentric loads, experimentally. is attributed fact that reduced mass reduces imposed lateral load during earthquakes, Literature review carried out in field order determine gaps or weak points commence this research.From...

In the embankment widening project, new will produce large deformation due to low degree of consolidation, which affect stability embankment. Obtaining settlement law is premise ensure this paper, studied through model test, and calculation method proposed. The test results show that old embankments have a difference during loading process, maximum twice lateral directly proportional vertical d...

Abstract This work aims to investigate the ultimate capacity of reinforced concrete elements in terms cracking and stiffness loss. Nonlinear finite element analysis (NLFEA) was performed ATENA software compared with a proposed numerical simulation nonlinear static (NLSA), where material is evaluated based on loss tangent elements. The applied low-rise frame constant axial loads columns, monoton...

Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...

This article investigates the flexural response of cantilevered top chord extensions open web steel joists used in building structures. Currently, no design guidance is available to assess bending capacity these members with consideration local and lateral-torsional buckling failure modes. The objective study was develop a numerical finite element model capable predicting behaviour 13 joist tes...

A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...
