In this paper, a new type of foam concrete (FC) incorporating ceramsite as a lightweight coarse aggregate was prepared, i.e. ceramsite cellular concrete (CCC). An experimental research was conducted on its thermal properties to clarify the correlation between thermal conductivity and density, compressive...

Since the 1970s, in Korea, a number of buildings were found to be built with materials containing a lot of asbestos, but few stuides have been made on how much arsenic acid a building has and how much asbestos is contained in building materials as the materials become degraded. The study aims to examine...

This study aims to predict demolition waste generation rate (DWGR) of the detached house by their types and materials when they are demolished. To achieve this objective, required data was collected based on material information of the buildings investigated before demolition. By using the established...

This work is aimed to optimize the heat treatment parameters of Ly12 (Al-Cu-Mg) alloy for improvement in properties. Also to study the aging behavior for determination of peak strength and highlighting the limitations of over-aging (over-burning). Normal composition of the alloy is 4.0 Cu, 0.7 Mn, 0.8...

This paper describes an integrated design approach, which aims to interpenetrate and reconstruct the boundaries of architectural design and structural engineering. There are four relevant experiments involved in this paper. The specific design strategies varies in this four practical projects: the first...

A facile hydrothermal method was successful to synthesize the TiO2 by using unique bacterial cellulose (BC) membranes as natural biotemplates. The three-dimensional networks of BC fibers coated with TiO2 nanoparticles can be clearly observed, resulting in the formation of uniform and well-defined hybrid...

After the completion and operation of the HSR (short for high-speed railway), a portion of passenger train flows in the existing parallel lines will transfer to the HSR, which is going to bring changes in the structure of train operation diagram, influences the carrying capacity of existing lines and...

Based on the nonlinear theory of cable-stayed bridge, nonlinear effects- cable sag, beam column effect, large displacement are calculated accurately using element geometric stiffness matrix, CR formulation, bar unit, Ernst formula and the catenary equation. Nonlinear analysis is applied on the study...

Base on plenty of field investigation and study, the loess cave dwellings were specifically divided into different types. Under the condition of continuous heavy rain, the loess cave dwelling destructions were summarized and analyzed to find out the reasons and the corresponding prevention measures.

In this paper, the work energy on the machined surface during electrical discharge machining (short in EDM) process were modeling analyzed based on the electron field emission theory, electron sputtering theory and the effect of resistance heat of electron current when the tool electrode is positive....

In this paper, the dynamic collapse behavior of the single layer reticulated shell with substructure which supports the reticulated shell is investigated under the earthquake actions....

The paper takes double curved arch bridge as the research object, including three kinds of strengthening reconstruction plans that changed the architecture form of the hyperbolic arch bridge. Using finite analysis software MIDAS/CIVIL to establish the finite element model of three kinds of reconstruction...

New method of quality improvement of the polymer modified binder (PMB) was considered in the paper. Testify to the fact that PMB modified by nanoagent is less sensitive to aging, as a result of the processes of peptization asphaltene-resin complexes (ARC) in the structure of the modified binder and the...

Currently, the new electro-optic properties of polymer dispersed liquid crystal (PDLC) have attracted considerable attention.
