| Summary: | 碩士 === 國立臺灣科技大學 === 建築系 === 98 === In the demands of post-earthquake reconstruction and low-rise residence, the steel residential building is gradually becoming important by compatriots, however, instead of the acceptability since the production and construction cost is higher. At present, most of the domestic residential steel construction firms lack of market competitiveness due to use the imported wall materials. Therefore, the major topic for run steel housing business is to reduce the production and construction cost.This research has laid out following three objectives:1.To analyze the cost and duration of wall construction through the unique wall system of Taiwan single steel residential building, the study tries to understand the potential problem and improvement of this system. 2. To reduce the production cost and shorten the duration as it’s final destination, the study proceeds the improved design with framed low-rise steel residential building through the “X-SAM” wall system. 3. To simulate and operate the “X-SAM” wall system in residential plan, which to inspect the benefit and the rate of duration.
The achievements in the research are listed as below: 1. Literature review, interview and case study are the methods adopted to analyze the cost and construction period of this wall system. Thus, the result shows potential problem is imported building materials (such as Ceramic wall plate system) and construction method from Japan, which raiser the cost also delay the duration ; Skeleton (C-channel) with 28.6% and Wall panels (Ceramic wall plate system) with 52.2% which constitute the highest proportion of construction cost. Therefore, it’s suggested that refine the construction of skeleton and wall system. 3. To proceed the improved design, the research has focused on three aspects: higher pre-produce degree, attempt diverse building materials such as Skeleton (various-channel) and Wall panels (External decoration wall system), also alter connected-method. To achieve the goal of cost down and higher the pre-dress, the exclusive “X-SAM” decoration wall materials will be modularized and prefabricated. 3. Three different scale residences has been designed to apply “X-SAM” in the deployment of residential plan, then the similar case was the sample to estimate the cost and duration. The final result shows that the unit cost of “X-SAM” is lower 12.48%（about 522 NTD$/m²）than the above-mentioned one, and the duration is shorten up to 43%（about 21 working days）.
