Monumentality and the Roman Empire: Architecture in the Antonine Age

The standard of "monumentality" is attributed to the constructions of few ancient epochs or cultures extra usually or always than to these of the Roman Empire. it really is this caliber that has helped to cause them to enduring types for developers of later sessions. This widely illustrated e-book, the 1st full-length examine of the idea that of monumentality in Classical Antiquity, asks what it really is that the inspiration encompasses and the way major it was once for the Romans themselves in molding their person or collective aspirations and identities.

How to Build With Bamboo: 19 Projects You Can Do at Home

Bamboo is "green gold" of the long run, with 60,000 species during the international, and actually hundreds of thousands of makes use of. No different plant turns out to have as many probabilities; it really is used for nutrients, building fabric, gas, floor, ornament, furnishings, and extra. this day, bamboo is charging into the western mainstream, and exploding in attractiveness.

Gert Wingårdh: Thirty Years of Architecture

Gert Wingårdh (*1951) is Swedens top architect. His smart and inventive spatial creations are striking in monetary in addition to ecological and sociological phrases. the focal point of his designs is often at the wishes of the long run clients. This monograph analyzes the imperative features of his paintings in seminal essays by means of popular structure critics and makes use of textual content and photographs to rfile all of the vital constructions of his thirty-year profession.

Simulation: Presentation Technique and Cognitive Method

Digitalization has remodeled the discourse of structure: that discourse is now outlined by means of a wealth of recent phrases and ideas that in the past both had no which means, or had assorted meanings, within the context of architectural thought and layout. Its ideas and techniques are more and more formed via affects rising on the intersection with medical and cultural notions from sleek details know-how.

Shallow Cobblestone Barrier. After the failure of the deep cobblestone barrier, the depth of the cobblestone surface treatment was reduced to 19 mm and retested by Caltrans. Typical relief of the shallow cobblestone surface is shown in Figure 52. In the pickup truck crash test of this barrier, the drive shaft became dislodged from the transmission. Although the vehicle remained upright during the test, this type of damage was considered by Caltrans to represent a potential rollover risk. As a result, Caltrans decided that the barrier did not meet NCHRP Report 350 evaluation criteria.

Noted that the interaction of the vehicle with this rail is considered to be substantially different than what typically occurs in an impact with a “solid” barrier. In the test of the Oregon barrier, the frame rail of the pickup truck protruded inside one of the “windows” and snagged severely on the inside of one of the concrete balusters. As a result, instead of the load going to the floorboard as it does in most OCD failures, the load was directed to the frame. Therefore, the Oregon bridge rail crash test was not taken into consideration when selecting the failure limit.

The ability to model the geometry of the safety shape barriers and the details of the aesthetic surface treatment (which affects the mechanics of the vehicle-barrier interaction) with a high degree of fidelity. • The availability of a large contact algorithm library. These contact algorithms provide means to model vehicular collisions with roadside objects. PILOT STUDY AND FINITE ELEMENT MODEL VALIDATION In all types of modeling, approximations must be made when trying to represent reality. If finite element analysis is to be used to assess the effects of surface treatments on concrete median barriers, the vehicle and barrier models must be capable of capturing the dynamic response associated with a concrete barrier impact.
